Dual-rail encoding with superconducting cavities
James D. Teoh, Patrick Winkel, Harshvardhan K. Babla +15
The design of quantum hardware that reduces and mitigates errors is essential for practical quantum error correction (QEC) and useful quantum computation. To this end, we introduce…
Study of noise in virtual distillation circuits for quantum error mitigation
Pontus Vikstål, Giulia Ferrini, Shruti Puri
Virtual distillation has been proposed as an error mitigation protocol for estimating the expectation values of observables in quantum algorithms. It proceeds by creating a cyclic…
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…
The squeezed Kerr oscillator: spectral kissing and phase-flip robustness
Nicholas E. Frattini, Rodrigo G. Cortiñas, Jayameenakshi Venkatraman +9
By applying a microwave drive to a specially designed Josephson circuit, we have realized an elementary quantum optics model, the squeezed Kerr oscillator. This model displays, as…
Estimating the bias of CX gates via character randomized benchmarking
Jahan Claes, Shruti Puri
Recent work has demonstrated that high-threshold quantum error correction is possible for biased-noise qubits, provided one can implement a controlled-not (CX) gate that preserves…
Scalable High-Performance Fluxonium Quantum Processor
Long B. Nguyen, Gerwin Koolstra, Yosep Kim +12
The technological development of hardware heading toward universal fault-tolerant quantum computation requires a large-scale processing unit with high performance. While fluxonium…
Observation of wave-packet branching through an engineered conical intersection
Christopher S. Wang, Nicholas E. Frattini, Benjamin J. Chapman +4
In chemical reactions, the interplay between coherent evolution and dissipation is central to determining key properties such as the rate and yield. Of particular interest are case…
Tailored cluster states with high threshold under biased noise
Jahan Claes, J. Eli Bourassa, Shruti Puri
Fault-tolerant cluster states form the basis for scalable measurement-based quantum computation. Recently, new stabilizer codes for scalable circuit-based quantum computation have…
Erasure conversion for fault-tolerant quantum computing in alkaline earth Rydberg atom arrays
Yue Wu, Shimon Kolkowitz, Shruti Puri +1
Executing quantum algorithms on error-corrected logical qubits is a critical step for scalable quantum computing, but the requisite numbers of qubits and physical error rates are d…
Ancilla-Error-Transparent Controlled Beam Splitter Gate
Iivari Pietikäinen, Ondřej Černotík, Shruti Puri +2
In hybrid circuit QED architectures containing both ancilla qubits and bosonic modes, a controlled beam splitter gate is a powerful resource. It can be used to create (up to a cont…
Swap-test interferometry with biased ancilla noise
Ondřej Černotík, Iivari Pietikäinen, Shruti Puri +2
The Mach--Zehnder interferometer is a powerful device for detecting small phase shifts between two light beams. Simple input states -- such as coherent states or single photons --…
