Hybrid Oscillator-Qubit Quantum Processors: Instruction Set Architectures, Abstract Machine Models, and Applications
Yuan Liu, Shraddha Singh, Kevin C. Smith +11
Quantum computing with discrete variable (DV, qubit) hardware is approaching the large scales necessary for computations beyond the reach of classical computers. However, important…
Efficient Implementation of a Quantum Algorithm with a Trapped Ion Qudit
Xiaoyang Shi, Jasmine Sinanan-Singh, Timothy J. Burke +2
Demonstration of quantum advantage remains challenging due to the increased overhead of controlling large quantum systems. While significant effort has been devoted to qubit-based…
Spontaneous Raman scattering from metastable states of Ba
Timothy J. Burke, Xiaoyang Shi, Jasmine Sinanan-Singh +2
Quantum logic gates performed via two-photon stimulated-Raman transitions in ions and atoms are fundamentally limited by spontaneous scattering errors. Recent theoretical treatment…
Long-lived metastable-qubit memory
Xiaoyang Shi, Jasmine Sinanan-Singh, Kyle DeBry +3
Coherent storage of quantum information is crucial to many quantum technologies. Long coherence times have been demonstrated in trapped-ion qubits, typically using the hyperfine le…
Single-shot Quantum Signal Processing Interferometry
Jasmine Sinanan-Singh, Gabriel L. Mintzer, Isaac L. Chuang +1
Quantum systems of infinite dimension, such as bosonic oscillators, provide vast resources for quantum sensing. Yet, a general theory on how to manipulate such bosonic modes for se…
