Symmetry as a route to generalized bosonic Kitaev chains
Gideon Lee, Tony Jin, Aashish A. Clerk
The bosonic Kitaev chain (BKC) model is a deceptively simple looking quadratic pairing Hamiltonian. Despite being purely Hermitian, it exhibits a number of striking non-Hermitian t…
Gauging the Spacetime Code
Gideon Lee
In recent years, the spacetime code has arisen as a candidate for a unifying view of fault tolerance in space and time. On the other hand, the recent study of dynamical phases has…
Quantum superresolution and noise spectroscopy with quantum computing
James W. Gardner, Federico Belliardo, Gideon Lee +2
Quantum metrology of an incoherent signal is a canonical sensing problem related to superresolution and noise spectroscopy. We show that quantum computing can accelerate searches f…
Timescales, Squeezing and Heisenberg Scalings in Many-Body Continuous Sensing
Gideon Lee, Ron Belyansky, Liang Jiang +1
The continuous monitoring of driven-dissipative systems offers new avenues for quantum advantage in metrology. This approach mixes temporal and spatial correlations in a manner dis…
Implementation of a quantum addressable router using superconducting qubits
Connie Miao, Sébastien Léger, Ziqian Li +3
The implementation of a quantum router capable of performing both quantum signal routing and quantum addressing (a Q2-router) represents a key step toward building quantum networks…
Analysis and Suppression of Errors in Quantum Random Access Memory under Extended Noise Models
Rohan Mehta, Gideon Lee, Liang Jiang
Quantum random access memory (QRAM) is required for numerous quantum algorithms and network architectures. Previous work has shown that the ubiquitous bucket-brigade QRAM is highly…
Performance and achievable rates of the Gottesman-Kitaev-Preskill code for pure-loss and amplification channels
Guo Zheng, Wenhao He, Gideon Lee +2
Quantum error correction codes protect information from realistic noisy channels and lie at the heart of quantum computation and communication tasks. Understanding the optimal perf…
The Near-optimal Performance of Quantum Error Correction Codes
Guo Zheng, Wenhao He, Gideon Lee +1
The Knill-Laflamme (KL) conditions distinguish exact quantum error correction codes, and it has played a critical role in the discovery of state-of-the-art codes. However, the fami…
Entanglement phase transition due to reciprocity breaking without measurement or post-selection
Gideon Lee, Tony Jin, Yu-Xin Wang +2
Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of non-Hermitian physics including non-reciprocal transport and the non-Hermitian skin eff…
Anomalously large relaxation times in dissipative lattice models beyond the non-Hermitian skin effect
Gideon Lee, Alexander McDonald, Aashish Clerk
We show for generic quantum non-Hermitian tight-binding models that relaxation timescales of local observables are not controlled by the localization length associate…
Error Suppression for Arbitrary-Size Black Box Quantum Operations
Gideon Lee, Connor T. Hann, Shruti Puri +2
Efficient suppression of errors without full error correction is crucial for applications with NISQ devices. Error mitigation allows us to suppress errors in extracting expectation…
Resilience of quantum random access memory to generic noise
Connor T. Hann, Gideon Lee, S. M. Girvin +1
Quantum random access memory (QRAM)--memory which stores classical data but allows queries to be performed in superposition--is required for the implementation of numerous quantum…
