Stroboscopic Stabilization of Cat Qubits
Timo Hillmann, Franco Nori, Fernando Quijandría
Dissipatively stabilized cat qubits provide a promising route toward fault-tolerant quantum computation, exhibiting exponential suppression of bit-flip errors with increasing phase…
Parallel distributed quantum gates for dual-species quantum emitters
Zhihao Xie, Adam Miranowicz, Zhenhua Li +2
We propose a parallel protocol for implementing distributed nonlocal quantum gates between spatially separated stationary qubits encoded in dual-species quantum emitters (i.e., col…
Resource efficient certification of system environment entanglement solely from reduced system dynamics
Jhen-Dong Lin, Pao-Wen Tu, Kuan-Yi Lee +4
Certifying nonclassical correlations typically requires access to all subsystems, presenting a major challenge in open quantum systems coupled to inaccessible environments. Recent…
Noise Protected Logical Qubit in a Open Chain of Superconducting Qubits with Ultrastrong Interactions
Roberto Stassi, Shilan Abo, Daniele Lamberto +4
To achieve a fault-tolerant quantum computer, it is crucial to increase the coherence time of quantum bits. In this work, we theoretically investigate a system consisting of a seri…
Heisenberg and Heisenberg-Like Representations via Hilbert Space Bundle Geometry in the Non-Hermitian Regime
Chia-Yi Ju, Adam Miranowicz, Jacob Barnett +2
The equivalence between the Schrödinger and Heisenberg representations is a cornerstone of quantum mechanics. However, this relationship remains unclear in the non-Hermitian regime…
Experimental simulation of postselected closed timelike curves for decoding scrambled quantum information
Yi-Te Huang, Hsiang-Wei Huang, Jhen-Dong Lin +5
Quantum information scrambling (QIS) describes the rapid spread of initially localized information across an entire quantum many-body system through entanglement generation. Once s…
