Outlier Robust Adversarial Training
Shu Hu, Zhenhuan Yang, Xin Wang +2
Supervised learning models are challenged by the intrinsic complexities of training data such as outliers and minority subpopulations and intentional attacks at inference time with…
Nonreciprocal waveguide-QED for spinning cavities with multiple coupling points
Wenxiao Liu, Yafen Lin, Jiaqi Li +1
We investigate chiral emission and the single-photon scattering of spinning cavities coupled to a meandering waveguide at multiple coupling points. It is shown that nonreciprocal p…
Spin-qubit noise spectroscopy from randomized benchmarking by supervised learning
Chengxian Zhang, Xin Wang
We demonstrate a method to obtain the spectra of noises in spin-qubit devices from randomized benchmarking, assisted by supervised learning. The noise exponent, which indicat…
Exact entanglement cost of quantum states and channels under PPT-preserving operations
Xin Wang, Mark M. Wilde
This paper establishes single-letter formulas for the exact entanglement cost of simulating quantum channels under free quantum operations that completely preserve positivity of th…
Two-color electromagnetically induced transparency via modulated coupling between a mechanical resonator and a qubit
Xin Wang, Adam Miranowicz, Hong-Rong Li +2
We discuss level splitting and sideband transitions induced by a modulated coupling between a superconducting quantum circuit and a nanomechanical resonator. First, we show how to…
Observing pure effects of counter-rotating terms without ultrastrong coupling: A single photon can simultaneously excite two qubits
Xin Wang, Adam Miranowicz, Hong-Rong Li +1
The coherent process that a single photon simultaneously excites two qubits has recently been theoretically predicted by [https://link.aps.org/doi/10.1103/PhysRevLett.117.043601 {P…
Hybrid quantum device with a carbon nanotube and a flux qubit for dissipative quantum engineering
Xin Wang, Adam Miranowicz, Hong-Rong Li +1
We describe a hybrid quantum system composed of a micrometer-size carbon nanotube (CNT) longitudinally coupled to a flux qubit. We demonstrate the usefulness of this device for gen…
Heralded quantum controlled phase gates with dissipative dynamics in macroscopically-distant resonators
Wei Qin, Xin Wang, Adam Miranowicz +2
Heralded near-deterministic multi-qubit controlled phase gates with integrated error detection have recently been proposed by Borregaard et al. [Phys. Rev. Lett. 114, 110502 (2015)…
Multi-output microwave single-photon source using superconducting circuits with longitudinal and transverse couplings
Xin Wang, Adam Miranowicz, Hong-Rong Li +1
Single-photon devices at microwave frequencies are important for applications in quantum information processing and communication in the microwave regime. In this work, we describe…
Method for observing robust and tunable phonon blockade in a nanomechanical resonator coupled to a charge qubit
Xin Wang, Adam Miranowicz, Hong-Rong Li +1
Phonon blockade is a purely quantum phenomenon, analogous to Coulomb and photon blockades, in which a single phonon in an anharmonic mechanical resonator can impede the excitation…
