Hidden-State Updates and observable-record composition in retrocausal models
A hidden-variable model can reproduce context-independent individual readouts while failing to preserve observable records when devices are connected or reused.No-signaling-in-time condition for three-flavor neutrino oscillations
Macrorealism is a fundamental concept in quantum foundations, capturing basic features of our everyday experience.Finite-blocklength classical communication over the quantum erasure channel with and without classical feedback
We determine the optimal success probability for transmitting a fixed number of classical messages through a finite number of uses of the quantum erasure channel, assisted by noiseless classical…Quantum Secret Sharing and Error Correction vs No-Cloning
Secret sharing is ubiquitous throughout cryptography.Robust classical and quantum communication over almost-iid channels
The independent and identically distributed (iid) paradigm for asymptotic communication through quantum channels describes $n$ uses of a channel $Φ$ by $Φ^{\otimes n}$.Flexible rigidity: Compiling generic trusted-preparation protocols into sequential device-independent protocols
We give a generic compiler for turning a wide class of device-dependent protocols with trusted state preparation into sequential device-independent protocols.Learning Local Fermionic Lindbladians under Parity Superselection
Parity superselection forbids direct measurement of odd Majorana observables.Clifford-hierarchy stabilizer formalism with applications to twisted quantum doubles
Recent work has shown that quantum double models can be used to circumvent the Bravyi-Koenig bound.Quantum Information in High-Energy Physics: a top subject
As a work selected for the Frontiers of Science Award, we present in the Proceedings of the ICBS an overview of how the techniques from the field of Quantum Information (QI) can be implemented in…Factor Code Networks
For a quantum code defined by an isometry $T:H_{\rm code} \to H_{\rm phys}$, an operator map is a *-homomorphism $\varphi: B(H_{\rm code}) \to B(H_{\rm phys})$ from the space of operators on the…Algebraic Relaxation of Strong-to-Weak Symmetry-Breaking Order via Charge-Sector Broadening
Strong-to-weak spontaneous symmetry breaking (SW-SSB) is a distinctive phenomenon of mixed quantum states, characterized by nonlinear long-range order associated with strong symmetry.Algebraic structure in holographic tensor networks
In a previous work 2511.21852, we explored the hypothesis that in general theories of quantum gravity, spacetime regions known as generalized entanglement wedges (introduced by Bousso and Penington)…Mixed-state phases induced by power-law quantum channels
Open quantum systems can exhibit inherently mixed quantum orders, such as strong-to-weak spontaneous symmetry breaking (SW-SSB), which have no analogue in pure states.Causal Trade-Offs in Superluminal Extensions of Relativity. A no-go theorem
Extensions of relativity that include superluminal reference frames have recently been proposed by Dragan and Ekert as a way to reconcile relativistic symmetry with quantum uncertainty.Quantum Algorithms for OPI Variants Beyond Locality and Classical Decodability
Regev's reduction quantumly finds codewords satisfying nonlinear constraints by decoding the dual code.Graph Neural Post-selection for Quantum Error Correction
Post-selection improves the logical reliability of quantum computation by rejecting shots which are likely to result in logical failure.Walshness: an intrinsic neural-network representability metric for quantum states
Neural quantum states (NQS) have emerged as powerful representations of quantum states with rapidly expanding applications across quantum many-body physics.Noisy Quantum Query Complexity via Fractional Block Sensitivity
We study quantum query complexity under several models of imperfect oracle access, and develop lower bounds through a common framework based on fractional block sensitivity ($\operatorname{fbs}$).Blind Unforgeability implies Plus-One Unforgeability
We prove that quantum blind-unforgeability implies quantum plus-one unforgeability, settling an open question in the literature.Near-Optimal Ground-State Preparation without Controlled Hamiltonian Evolutions
Ground-state preparation, energy estimation, and property estimation are fundamental tasks in quantum simulation.
