Real-Time Adaptive Filtering and the Boxcar Limit in Superconducting Qubit Readout
Hans Johnson, Tanay Roy, Leonardo Bove +3
Control and readout systems for superconducting quantum computing support real-time control and high-fidelity qubit-state discrimination. We examine when additional digital process…
Microwave dielectric properties of LiNbO and AlN at millikelvin temperatures and single-photon power
Alessandro Reineri, Francesco Crisa, Akshay Murthy +8
Efficient bidirectional microwave-optical photon conversion is a key capability for scaling superconducting quantum processors into distributed networks. However, achieving the nec…
Exact Fock-State Preparation with Circuit Depth
Tanay Roy
Efficient, deterministic, and high-fidelity preparation of large Fock states is essential for scaling bosonic quantum technologies and exploring quantum phenomena at large excitati…
Architectural scaling tradeoffs in modular 3D bosonic quantum processors
Shaojiang Zhu, Ugur Alyanak, Tanay Roy +7
We propose a modular three-dimensional bosonic quantum processor built from repeatable coupled-cavity modules linked by configurable interconnect networks. Using hardware-motivated…
Dissipation Enables Strongly Detuning-Dependent Interference in Pulsed Dynamical Decoupling
Kenneth DeRose, Jonah Glick, Kefeng Jiang +6
One of the defining features of pulsed dynamical decoupling is its suppression of a driven qubit's sensitivity to static detuning errors between the drive field and qubit resonance…
Universal Jaynes-Cummings Control of an Oscillator
Jordan Huang, Ethan Kasaba, Thomas J. DiNapoli +2
The Jaynes-Cummings (JC) interaction-the coherent exchange of excitations between a two-level system and a harmonic oscillator-is one of the fundamental interactions of quantum opt…
Sparse Phase Ansatzes for Resource-Efficient Qudit State Preparation via the SNAP-Displacement Protocol
Maurizio Ferrari Dacrema, Doga Murat Kurkcuoglu, Andy C. Y. Li +2
Efficient preparation of nonclassical bosonic states is a central requirement for quantum computing, simulation, and precision metrology. We study resource-efficient quantum state…
Two-Level System Spectroscopy from Correlated Multilevel Relaxation in Superconducting Qubits
Tanay Roy, Xinyuan You, David van Zanten +5
Transmon qubits are a cornerstone of modern superconducting quantum computing platforms. Temporal fluctuations of energy relaxation in these qubits are widely attributed to microsc…
