Optimal conversion of Kochen-Specker sets into bipartite perfect quantum strategies
Stefan Trandafir, A. Cabello·Oct 22, 2024
Bipartite perfect quantum strategies (BPQSs) allow two players isolated from each other to win every trial of a nonlocal game. BPQSs have crucial roles in recent developments in quantum information and quantum computation. However, only few BPQSs wit...
Measuring error rates of mid-circuit measurements
Daniel Hothem, Jordan Hines, Charles Baldwin +3 more·Oct 22, 2024
High-fidelity mid-circuit measurements, which read out the state of specific qubits in a multiqubit processor without destroying them or disrupting their neighbors, are a critical component for useful quantum computing. They enable fault-tolerant qua...
TE-PAI: exact time evolution by sampling random circuits
Chusei Kiumi, Bálint Koczor·Oct 22, 2024
Simulating time evolution under quantum Hamiltonians is one of the most natural applications of quantum computers. We introduce TE-PAI, which simulates time evolution exactly by sampling random quantum circuits for the purpose of estimating observabl...
Scalable Constant-Time Logical Gates for Large-Scale Quantum Computation Using Window-Based Correlated Decoding
Jiaxuan Zhang, Zhao-Yun Chen, Jia-Ning Li +6 more·Oct 22, 2024
Large-scale quantum computation requires to be performed in the fault-tolerant manner. One crucial challenge of fault-tolerant quantum computing (FTQC) is reducing the overhead of implementing logical gates. Recently work proposed correlated decoding...
Semidefinite optimization of the quantum relative entropy of channels
Gereon Koßmann, Mark M. Wilde·Oct 21, 2024
This paper introduces a method for calculating the quantum relative entropy of channels, an essential quantity in quantum channel discrimination and resource theories of quantum channels. By building on recent developments in the optimization of rela...
Integer Factorization via Tensor Network Schnorr's Sieving
Marco Tesoro, Ilaria Siloi, Daniel Jaschke +2 more·Oct 21, 2024
Classical public-key cryptography standards rely on the Rivest-Shamir-Adleman (RSA) encryption protocol. The security of this protocol is based on the exponential computational complexity of the most efficient classical algorithms for factoring large...
Scalable and deterministic Greenberger-Horne-Zeilinger state generation via graph states-assisted measurements
Harikrishnan K J, Amit Kumar Pal·Oct 21, 2024
We propose a scalable and deterministic protocol for growing large multi-qubit states starting from two-qubit non-maximally entangled pure states, where the bipartite entanglement in the resultant state is higher than the maximum of the available ent...
Monogamy of Entanglement Bounds and Improved Approximation Algorithms for Qudit Hamiltonians
Zackary Jorquera, Alexandra Kolla, Steven Kordonowy +2 more·Oct 21, 2024
We prove new monogamy of entanglement bounds for two-local qudit Hamiltonians of rank-one projectors without one-local terms. In particular, we certify the maximum energy in terms of the maximum matching of the underlying interaction graph via low-de...
Maximally entangled gluons for any $x$
Yoshitaka Hatta, Jake Montgomery·Oct 21, 2024
Individual quarks and gluons at small-$x$ inside an unpolarized hadron can be regarded as Bell states in which qubits in the spin and orbital angular momentum spaces are maximally entangled. Using the machinery of quantum information science, we gene...
