abstract = {We consider two related problems of extracting correlation from a given multipartite mixed quantum state: the first is the distillation of a conference key when the state is shared between a number of legal players and an eavesdropper; the eavesdropper, apart from starting off with this quantum side information, also observes the public communication between the players. The second is the distillation of Greenberger-Horne-Zeilinger (GHZ) states by means of LOCC from the given mixed state. These problem settings extend our previous paper [FS & AW, IEEE Trans. Inf. Theory 68(2):976-988, 2022], and we generalise its results: using a quantum version of the task of communication for omniscience, we derive a novel lower bound on the distillable secret key from any multipartite quantum state by means of a so-called non-interacting communication protocol. Secondly, by making the secret key distillation protocol coherent, we derive novel lower bounds on the distillation rate of GHZ states.},

abstract = {Among the strangest properties of quantum mechanics there is certainly the fact that acting on a quantum system disturbs it. This phenomenon has always been at the center of an extremely active line of research, and only recently, thanks to quantum information analysis tools, we have begun to understand it more deeply. In our work we continued the characterization of this property by demonstrating that this disturbance action is logically independent from the property of complementarity, i.e. the existence of couples of observables that is impossible to measure simultaneously. To do this we have built two different toy theories, called Minimal Classical Theory and Minimal Strongly-causal Bilocal Classical Theory within the framework of operational probabilistic theories, which posses the former property, but not the latter.},

abstract = {In the context of Quantum Communication theory, a lossy channel is a quantum channel that can describe a wide variety of scenarios that cause an attenuation of the input signal, such as the transmission in an optical fiber or free-space communication. From the mathematical point of view, a lossy channel is described as an interaction, mediated by a beam-splitter with fixed transmissivity, between the input state and the environment state, which is the vacuum state.
In some realistic situations, as the transmission of photons through the atmosphere, the noise that affects the quantum carrier cannot be described by a single lossy channel, because of the fluctuations in the loss parameter. Therefore, it is better to model these scenarios considering an ensemble of lossy channels.
The classical capacity of a quantum channel is the asymptotic rate of transmission of classical information, sent from a sender to a receiver, when the quantum system that carries the information is subject to the noise described by the quantum channel. If sender and receiver share an unlimited amount of entanglement that can be used to improve the communication, one can define the entanglement-assisted classical capacity. In this work, we studied some families of channels, that are convex combinations of two different lossy channels and, in order to describe such a convex combination, we used an ancillary qubit that selects one or the other channel. We found that, for those channels, there exist quantum states with a better communication performance with respect to the thermal state with the same energy; this is surprising because it is known that a thermal state is the best choice for a single lossy channel. However, using the methods developed in this work, it is possible to model even more general scenarios, in order to improve the quantum communication performance of more realistic noises.},

abstract = {We investigate the two-sided symmetric extendibility problem of Werner states. The interplay of the unitary symmetry of these states and the inherent bipartite permutation symmetry of the extendibility scenario allows us to map this problem into the ground state problem of a highly symmetric spin-model Hamiltonian. We solve this ground state problem analytically by utilizing the representation theory of SU(d), in particular a result related to the dominance order of Young diagrams in Littlewood-Richarson decompositions. As a result, we obtain necessary and sufficient conditions for the extendibility of Werner states for arbitrary extension size and local dimension. Interestingly, the range of extendible states has a non-trivial trade-off between the extension sizes on the two sides. We compare our result with the two-sided extendibility problem of isotropic states, where there is no such trade-off.},

While the former is required for passive polarization encoding, the latter is necessary to tightly estimate the secret key rate in the absence of perfect single-photon sources. In addition, we provide a novel parameter estimation technique and non-asymptotic bounds on the secret key length.},

abstract = {Continuous Variable (CV) quantum key distribution (QKD) is a promising candidate for practical implementations due to its compatibility with the existing communication technology. A trusted device scenario assuming that an adversary has no access to imperfections such as electronic noises in the detector is expected to provide significant improvement in the key rate, but such an endeavor so far was made separately for specific protocols and for specific proof techniques. Here, we develop a simple and general treatment that can incorporate the effects of Gaussian trusted noises for any protocol that uses homodyne/heterodyne measurements. In our method, a rescaling of the outcome of a noisy homodyne/heterodyne detector renders it equivalent to the outcome of a noiseless detector with a tiny additional loss, thanks to a noise-loss equivalence well-known in quantum optics. Since this method is independent of protocols and security proofs, it is applicable to Gaussian-modulation and discrete-modulation protocols, to the finite-size regime, and to any proof techniques developed so far and yet to be discovered as well.},

Here we show that such a result does not generalize to quartic polynomials and 2-query algorithms, even when we allow for additive approximations. We also show that the additive approximation implied by their result is tight for bounded bilinear forms, which gives a new characterization of the Grothendieck constant in terms of 1-query quantum algorithms. Along the way we provide reformulations of the completely bounded norm of a form, and its dual norm.},

abstract = {Efficient certification and quantification of high dimensional entanglement of composite systems are challenging both theoretically as well as experimentally. Here, we demonstrate how to measure the linear entropy, negativity and the Schmidt number of bipartite systems from the visibility of Mach–Zehnder interferometer using single copies of the quantum state. Our result shows that for any two qubit pure bipartite state, the interference visibility is a direct measure of entanglement. We also propose how to measure the mutual predictability experimentally from the intensity patterns of the interferometric set-up without having to resort to local measurements of mutually unbiased bases. Furthermore, we show that the entanglement witness operator can be measured in a interference setup and the phase shift is sensitive to the separable or entangled nature of the state. Our proposal bring out the power of Interferometric set-up in entanglement detection of pure and several mixed states which paves the way towards design of entanglement meter.},

Our main contribution is a new generation of deterministic, high-precision QITE algorithms that are significantly more amenable experimentally.

This causes a huge reduction in wasted circuit depth every time a run fails.

abstract = {Decoy-state quantum key distribution (QKD) is undoubtedly the most efficient solution to han- dle multi-photon signals emitted by laser sources, and provides the same secret key rate scaling as ideal single-photon sources. It requires, however, that the phase of each emitted pulse is uniformly random. This might be difficult to guarantee in practice, due to inevitable device imperfections and/or the use of an external phase modulator for phase randomization, which limits the possible selected phases to a finite set. Here, we investigate the security of decoy-state QKD with arbitrary, continuous or discrete, non-uniform phase randomization, and show that this technique is quite robust to deviations from the ideal uniformly random scenario. For this, we combine a novel param- eter estimation technique based on semi-definite programming, with the use of basis mismatched events, to tightly estimate the parameters that determine the achievable secret key rate. In doing so, we demonstrate that our analysis can significantly outperform previous results that address more restricted scenarios.},

abstract = {In superconducting architectures, limited connectivity remains a significant challenge for the synthesis and compilation of quantum circuits. We consider models of entanglement-assisted computation where long-range operations are achieved through injections of entangled CAT states. These are prepared using ancillary qubits acting as an "entanglement bus," unlocking global operation primitives such as multi-qubit Pauli rotations and fan out gates. We derive bounds on the circuit size for several well-studied problems, such as CZ circuit, CX circuit, and Clifford circuit synthesis. In particular, in an architecture using one such entanglement bus, we show that Clifford operations require at most $2n+1$ layers of entangled-state-injections, significantly improving upon the best known SWAP-based approaches which achieve an entangling-gate-depth of $7n−4$. In a square-lattice architecture with two entanglement buses, we show that a graph state can be synthesized using at most $łceil n/2 rceil +1$ layers of CAT state injections, and Clifford operations require only $łceil 3n/2 rceil +O(sqrtn)$ layers of CAT state injections.},
