Preservability of Measurement Incompatibility: Purification, Activation, and a No-Go Theorem
Chao-Hsien Wu, Franco Nori, Huan-Yu Ku
Measurement incompatibility is a fundamental quantum resource that enables advantages in many quantum information tasks, including cryptography and communication. However, unavoida…
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…
Resource-efficient quantum correlation measurements via multicopy neural network methods
Patrycja Tulewicz, Karol Bartkiewicz, Adam Miranowicz +1
Measuring complex properties in quantum systems, such as measures of quantum entanglement and Bell nonlocality, is inherently challenging. Traditional methods, like quantum state t…
Non-Markovian Quantum Exceptional Points
Jhen-Dong Lin, Po-Chen Kuo, Neill Lambert +3
Exceptional points (EPs) are singularities in the spectra of non-Hermitian operators, where eigenvalues and eigenvectors coalesce. Recently, open quantum systems have been increasi…
Restoring Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Ievgen I. Arkhipov, Fabrizio Minganti, Adam Miranowicz +2
Non-Hermitian systems have attracted much interest in recent decades, driven partly by the existence of exotic spectral singularities, known as exceptional points (EPs), where the…
Exponentially Improved Dispersive Qubit Readout with Squeezed Light
Wei Qin, Adam Miranowicz, Franco Nori
It has been a long-standing goal to improve dispersive qubit readout with squeezed light. However, injected external squeezing (IES) {\it cannot} enable a practically interesting i…

Xin Wang, Jia-Qi Li, Tao Liu +2
Multi-photon dynamics beyond linear optical materials are of significant fundamental and technological importance in quantum information processing. However, it remains largely une…
Unveiling quantum steering by quantum-classical uncertainty complementarity
Kuan-Yi Lee, Jhen-Dong Lin, Karel Lemr +5
One of the remarkable aspects of quantum steering is its ability to violate local uncertainty complementarity relations. In this vein of study, various steering witnesses have been…
