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 […]
Quantum 5, 400 (2021). https://doi.org/10.22331/q-2021-02-24-400 The Gottesman-Knill theorem states that a Clifford circuit acting on stabilizer states can be simulated efficiently on a classical computer. Recently, this result has been generalized to cover inputs that […]
Quantum 5, 399 (2021). https://doi.org/10.22331/q-2021-02-22-399 Simulating the dynamics and the non-equilibrium steady state of an open quantum system are hard computational tasks on conventional computers. For the simulation of the time evolution, several efficient quantum […]
