Charge-Informed Quantum Error Correction
Vlad Temkin, Zack Weinstein, Ruihua Fan +2
We investigate the statistical physics of quantum error correction in symmetry-enriched topological quantum memories. Starting from a phenomenological error model of c…
Spectral properties and coding transitions of Haar-random quantum codes
Grace M. Sommers, J. Alexander Jacoby, Zack Weinstein +2
A quantum error-correcting code with a nonzero error threshold undergoes a mixed-state phase transition when the error rate reaches that threshold. We explore this phase transition…
Efficient Detection of Strong-To-Weak Spontaneous Symmetry Breaking via the Rényi-1 Correlator
Zack Weinstein
Strong-to-weak spontaneous symmetry breaking (SWSSB) has recently emerged as a universal feature of quantum mixed-state phases of matter. While various information-theoretic diagno…
Scrambling Transition in a Radiative Random Unitary Circuit
Zack Weinstein, Shane P. Kelly, Jamir Marino +1
We study quantum information scrambling in a random unitary circuit that exchanges qubits with an environment at a rate . As a result, initially localized quantum information no…
Measurement-Induced Power-Law Negativity in an Open Monitored Quantum Circuit
Zack Weinstein, Yimu Bao, Ehud Altman
Generic many-body systems coupled to an environment lose their quantum entanglement due to decoherence and evolve to a mixed state with only classical correlations. Here, we show t…
Universality Classes of Stabilizer Code Hamiltonians
Zack Weinstein, Gerardo Ortiz, Zohar Nussinov
Stabilizer code quantum Hamiltonians have been introduced with the intention of physically realizing a quantum memory because of their resilience to decoherence. In order to analyz…
