Channel-based framework for phase esimation of multiple eigenvalues
Yuan-De Jin, Shi-Yu Zhang, Wen-Long Ma
Quantum phase estimation (QPE) of the eigenvalues of a unitary operator on a target quantum system is a crucial subroutine in various quantum algorithms. Conventional QPE is often…
Sequential generalized measurements: Asymptotics, typicality and emergent projective measurements
Wen-Long Ma, Shu-Shen Li, Ren-Bao Liu
The relation between projective measurements and generalized quantum measurements is a fundamental problem in quantum physics, and clarifying this issue is also important to quantu…
Algebraic structure of path-independent quantum control
Wen-Long Ma, Shu-Shen Li, Liang Jiang
Path-independent (PI) quantum control has recently been proposed to integrate quantum error correction and quantum control [Phys. Rev. Lett. 125, 110503 (2020)], achieving fault-to…
Quantum control of bosonic modes with superconducting circuits
Wen-Long Ma, Shruti Puri, Robert J. Schoelkopf +3
Bosonic modes have wide applications in various quantum technologies, such as optical photons for quantum communication, magnons in spin ensembles for quantum information storage a…
Multimode photon blockade
Srivatsan Chakram, Kevin He, Akash V. Dixit +7
Interactions are essential for the creation of correlated quantum many-body states. While two-body interactions underlie most natural phenomena, three- and four-body interactions a…
Cluster-correlation expansion for studying decoherence of clock transitions in spin baths
Geng-Li Zhang, Wen-Long Ma, Ren-Bao Liu
The clock transitions (CTs) of central spins have long coherence times because their frequency fluctuations vanish in the linear order of external field noise (such as Overhauser f…
Path-Independent Quantum Gates with Noisy Ancilla
Wen-Long Ma, Mengzhen Zhang, Yat Wong +5
Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, whi…
Error-corrected gates on an encoded qubit
Philip Reinhold, Serge Rosenblum, Wen-Long Ma +3
To solve classically hard problems, quantum computers need to be resilient to the influence of noise and decoherence. In such a fault-tolerant quantum computer, noise-induced error…
Phase transitions in sequential weak measurements
Wen-Long Ma, Ping Wang, Weng-Hang Leong +1
Quantum measurements and phase transitions are seemingly uncorrelated topics, but here we show that phase transitions occur in sequential quantum measurements. We find that the pro…
Single-Shot Readout of a Nuclear Spin Weakly Coupled to a Nitrogen-Vacancy Center
Gang-Qin Liu, Jian Xing, Wen-Long Ma +5
Single-shot readout of qubits is required for scalable quantum computing. Nuclear spins are superb quantum memories due to their long coherence times but are difficult to be read o…
Quantum many-body theory for electron spin decoherence in nanoscale nuclear spin baths
Wen Yang, Wen-Long Ma, Ren-Bao Liu
Decoherence of electron spins in nanoscale systems is important to quantum technologies such as quantum information processing and magnetometry. It is also an ideal model problem f…
Proposal for Quantum Sensing Based on Two-Dimensional Dynamical Decoupling: NMR Correlation Spectroscopy of Single Molecules
Wen-Long Ma, Ren-Bao Liu
Nuclear magnetic resonance (NMR) has enormous applications. Two-dimensional NMR is an essential technique to characterize correlations between nuclei and, hence, molecule structure…
Angstrom-resolution magnetic resonance imaging of single molecules via wavefunction fingerprints of nuclear spins
Wen-Long Ma, Ren-Bao Liu
Single-molecule sensitivity of nuclear magnetic resonance (NMR) and angstrom resolution of magnetic resonance imaging (MRI) are the highest challenges in magnetic microscopy. Recen…
Atomic-scale positioning of single spins via multiple nitrogen-vacancy centers
Wen-Long Ma, Shu-Shen Li, Geng-Yu Cao +1
We present a scheme of positioning a single electron spin with sub-nanometer resolution through multiple nitrogen-vacancy centers in diamond. With unwanted noise suppressed by dyna…
The classical nature of nuclear spin noise near clock transitions of Bi donors in silicon
Wen-Long Ma, Gary Wolfowicz, Shu-Shen Li +2
Whether a quantum bath can be approximated as classical noise is a fundamental issue in central spin decoherence and also of practical importance in designing noise-resilient quant…
Uncovering many-body correlations in nanoscale nuclear spin baths by central spin decoherence
Wen-Long Ma, Gary Wolfowicz, Nan Zhao +3
Many-body correlations can yield key insights into the nature of interacting systems; however, detecting them is often very challenging in many-particle physics, especially in nano…
