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…
Resist-free shadow deposition using silicon trenches for Josephson junctions in superconducting qubits
Tathagata Banerjee, Stephen Daniel Funni, Saswata Roy +2
Superconducting qubit fabrication innovations continue to be explored to achieve higher performance. Despite improvements to base layer fabrication and processing, resist-based Jos…
Error semitransparent universal control of a bosonic logical qubit
Saswata Roy, Owen C. Wetherbee, Valla Fatemi
Bosonic codes offer hardware-efficient approaches to logical qubit construction and hosted the first demonstration of beyond-break even logical quantum memory. However, such accomp…
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…
Krypton-sputtered tantalum films for scalable high-performance quantum devices

A Mathematical Structure for Amplitude-Mixing Error-Transparent Gates for Binomial Codes
Owen C. Wetherbee, Saswata Roy, Baptiste Royer +1
Bosonic encodings of quantum information offer hardware-efficient, noise-biased approaches to quantum error correction relative to qubit register encodings. Implementations have fo…
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…
