Quantum 5, 410 (2021). https://doi.org/10.22331/q-2021-03-15-410 Tensor networks represent the state-of-the-art in computational methods across many disciplines, including the classical simulation of quantum many-body systems and quantum circuits. Several applications of current interest give rise to […]
Quantum 5, 409 (2021). https://doi.org/10.22331/q-2021-03-11-409 The framework of quantum invariants is an elegant generalization of adiabatic quantum control to control fields that do not need to change slowly. Due to the unavailability of invariants for […]
Quantum 5, 408 (2021). https://doi.org/10.22331/q-2021-03-10-408 In stochastic thermodynamics work is a random variable whose average is bounded by the change in the free energy of the system. In most treatments, however, the work reservoir that […]
Quantum 5, 407 (2021). https://doi.org/10.22331/q-2021-03-10-407 The optimal allocation of resources is a crucial task for their efficient use in a wide range of practical applications in science and engineering. This paper investigates the optimal allocation […]
Quantum 5, 406 (2021). https://doi.org/10.22331/q-2021-03-10-406 Homological product codes are a class of codes that can have improved distance while retaining relatively low stabilizer weight. We show how to build union-find decoders for these codes, using […]
Quantum 5, 405 (2021). https://doi.org/10.22331/q-2021-03-10-405 The commodity-based cryptography is an alternative approach to realize conventionally impossible cryptographic primitives such as unconditionally secure bit-commitment by consuming pre-established correlation between distrustful participants. A unit of such classical […]
Quantum 5, 404 (2021). https://doi.org/10.22331/q-2021-03-08-404 The double slit experiment provides a clear demarcation between classical and quantum theory, while multi-slit experiments demarcate quantum and higher-order interference theories. In this work we show that these experiments […]
Quantum 5, 403 (2021). https://doi.org/10.22331/q-2021-03-07-403 We study the query complexity of quantum learning problems in which the oracles form a group $G$ of unitary matrices. In the simplest case, one wishes to identify the oracle, […]
Quantum 5, 402 (2021). https://doi.org/10.22331/q-2021-03-07-402 An $noverset{p}{mapsto}m$ random access code (RAC) is an encoding of $n$ bits into $m$ bits such that any initial bit can be recovered with probability at least $p$, while in […]
Quantum 5, 401 (2021). https://doi.org/10.22331/q-2021-03-02-401 Self-testing is a method to certify devices from the result of a Bell test. Although examples of noise tolerant self-testing are known, it is not clear how to deal efficiently […]
