Demonstrating RFSoC-based Control of a Fully Connected Exchange-Only Qubit
Abigail L. Wessels, M. Garrett Bimstefer, Joseph D. Broz +2
Semiconductor triple-quantum dots (TQDs) are a promising platform for scalable quantum information processing, but the community has so far lacked access to affordable and flexible…
Quantum sensors that compute: quantum computational magnetic-field sensing using a superconducting qubit
Purnendu Sen, Mathieu Ouellet, Saeed A. Khan +6
A measurement of a single-qubit quantum sensor reveals at most 1 bit of information about the signal that was sensed. To perform a classification task on the signal, the convention…
Exponential quantum advantage for learning signals with a single qubit
Ishaan Kannan, Sridhar Prabhu, Saeed A. Khan +7
Quantum technology has the potential to transform scientific discovery, but quantum advantages often require processing capabilities well beyond the reach of experimental platforms…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
Quantum computational displacement sensing
Sridhar Prabhu, Saeed A. Khan, Xingrui Song +7
Quantum computational sensing (QCS) combines quantum sensing with quantum computing to extract task-relevant information from the physical world. QCS can in principle achieve an ac…
Synthetic high angular momentum spin dynamics in a microwave oscillator
Saswata Roy, Alen Senanian, Christopher S. Wang +10
Spins and oscillators are foundational to much of physics and applied sciences. For quantum information, a spin 1/2 exemplifies the most basic unit, a qubit. High angular momentum…
Microwave signal processing using an analog quantum reservoir computer
Alen Senanian, Sridhar Prabhu, Vladimir Kremenetski +8
Quantum reservoir computing (QRC) has been proposed as a paradigm for performing machine learning with quantum processors where the training is efficient in the number of required…
Programmable large-scale simulation of bosonic transport in optical synthetic frequency lattices
Alen Senanian, Logan G. Wright, Peter F. Wade +2
Photonic simulators using synthetic frequency dimensions have enabled flexible experimental analogues of condensed-matter systems, realizing phenomena that are impractical to obser…
Analysis of Magnetic Vortex Dissipation in Sn-Segregated Boundaries in NbSn Superconducting RF Cavities
Jared Carlson, Alden Pack, Mark K. Transtrum +9
We study mechanisms of vortex nucleation in NbSn Superconducting RF (SRF) cavities using a combination of experimental, theoretical, and computational methods. Scanning transmi…
Vortex dynamics and losses due to pinning: Dissipation from trapped magnetic flux in resonant superconducting radio-frequency cavities
Danilo B. Liarte, Daniel Hall, Peter N. Koufalis +4
We use a model of vortex dynamics and collective weak pinning theory to study the residual dissipation due to trapped magnetic flux in a dirty superconductor. Using simple estimate…
Glassy dynamics in disordered oscillator chains
Alen Senanian, Onuttom Narayan
The escape of energy injected into one site in a disordered chain of nonlinear oscillators is examined numerically. When the disorder has a `fractal' pattern, the decay of the resi…
