Ancilla-free quantum error correction codes for quantum metrology
David Layden, Sisi Zhou, Paola Cappellaro +1
Quantum error correction has recently emerged as a tool to enhance quantum sensing under Markovian noise. It works by correcting errors in a sensor while letting a signal imprint o…
Enhanced energy-constrained quantum communication over bosonic Gaussian channels
Kyungjoo Noh, Stefano Pirandola, Liang Jiang
Quantum communication is an important branch of quantum information science, promising unconditional security to classical communication and providing the building block of a futur…
Quantum repeater architecture with hierarchically optimized memory buffer times
Siddhartha Santra, Liang Jiang, Vladimir Malinovsky
We propose a quantum repeater protocol and architecture that mitigates decoherence of the entangled states by optimizing the quantum memory buffer time. The protocol maximizes the…
Saturating the quantum Cramér-Rao bound using LOCC
Sisi Zhou, Chang-Ling Zou, Liang Jiang
The quantum Cramér-Rao bound (QCRB) provides an ultimate precision limit allowed by quantum mechanics in parameter estimation. Given any quantum state dependent on a single paramet…
Engineering bilinear mode coupling in circuit QED: Theory and experiment
Yaxing Zhang, Brian J. Lester, Yvonne Y. Gao +3
Photonic states of superconducting microwave cavities controlled by transmon ancillas provide a platform for encoding and manipulating quantum information. A key challenge in scali…
Stabilized Cat in Driven Nonlinear Cavity: A Fault-Tolerant Error Syndrome Detector
Shruti Puri, Alexander Grimm, Philippe Campagne-Ibarcq +7
In quantum error correction, information is encoded in a high-dimensional system to protect it from the environment. A crucial step is to use natural, low-weight operations with an…
Entangling Bosonic Modes via an Engineered Exchange Interaction
Yvonne Y. Gao, Brian J. Lester, Kevin Chou +5
The realization of robust universal quantum computation with any platform ultimately requires both the coherent storage of quantum information and (at least) one entangling operati…
All-Optical control of linear and nonlinear energy transfer via Zeno effect
Xiang Guo, Chang-Ling Zou, Liang Jiang +1
Microresonator-based nonlinear processes are fundamental to applications including microcomb generation, parametric frequency conversion, and harmonics generation. While nonlinear…
Fault-tolerant detection of a quantum error
S. Rosenblum, P. Reinhold, M. Mirrahimi +3
A critical component of any quantum error-correcting scheme is detection of errors by using an ancilla system. However, errors occurring in the ancilla can propagate onto the logic…
Improved quantum capacity bounds of Gaussian loss channels and achievable rates with Gottesman-Kitaev-Preskill codes
Kyungjoo Noh, Victor V. Albert, Liang Jiang
Gaussian loss channels are of particular importance since they model realistic optical communication channels. Except for special cases, quantum capacity of Gaussian loss channels…
Programmable interference between two microwave quantum memories
Yvonne Y. Gao, B. J. Lester, Yaxing Zhang +6
Interference experiments provide a simple yet powerful tool to unravel fundamental features of quantum physics. Here we engineer an RF-driven, time-dependent bilinear coupling that…
Deterministic teleportation of a quantum gate between two logical qubits
K. S. Chou, J. Z. Blumoff, C. S. Wang +7
A quantum computer has the potential to effciently solve problems that are intractable for classical computers. Constructing a large-scale quantum processor, however, is challengin…
One way quantum repeaters with quantum Reed-Solomon codes
Sreraman Muralidharan, Chang-Ling Zou, Linshu Li +1
We show that quantum Reed-Solomon codes constructed from classical Reed-Solomon codes can approach the capacity on the quantum erasure channel of -level systems for large dimens…
Pair-cat codes: autonomous error-correction with low-order nonlinearity
Victor V. Albert, Shantanu O. Mundhada, Alexander Grimm +3
We introduce a driven-dissipative two-mode bosonic system whose reservoir causes simultaneous loss of two photons in each mode and whose steady states are superpositions of pair-co…
A modern description of Rayleigh's criterion
Sisi Zhou, Liang Jiang
Rayleigh's criterion states that it becomes essentially difficult to resolve two incoherent optical point sources separated by a distance below the width of point spread functions…
