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…
A parametrically programmable delay line for microwave photons
Takuma Makihara, Nathan Lee, Yudan Guo +2
Delay lines that store quantum information are crucial for advancing quantum repeaters and hardware efficient quantum computers. Traditionally, they are realized as extended system…
Surface Modification and Coherence in Lithium Niobate SAW Resonators
Rachel G. Gruenke, Oliver A. Hitchcock, E. Alex Wollack +5
Lithium niobate is a promising material for developing quantum acoustic technologies due to its strong piezoelectric effect and availability in the form of crystalline thin films o…
Strong dispersive coupling between a mechanical resonator and a fluxonium superconducting qubit
Nathan R. A. Lee, Yudan Guo, Agnetta Y. Cleland +10
We demonstrate strong dispersive coupling between a fluxonium superconducting qubit and a 690 megahertz mechanical oscillator, extending the reach of circuit quantum acousto-dynami…
Analysis of arbitrary superconducting quantum circuits accompanied by a Python package: SQcircuit
Taha Rajabzadeh, Zhaoyou Wang, Nathan Lee +3
Superconducting quantum circuits are a promising hardware platform for realizing a fault-tolerant quantum computer. Accelerating progress in this field of research demands general…
High-bandwidth CMOS-voltage-level electro-optic modulation of 780 nm light in thin-film lithium niobate
Oguz Tolga Celik, Christopher J. Sarabalis, Felix M. Mayor +7
Integrated photonics operating at visible-near-infrared (VNIR) wavelengths offer scalable platforms for advancing optical systems for addressing atomic clocks, sensors, and quantum…
Automated discovery of autonomous quantum error correction schemes
Zhaoyou Wang, Taha Rajabzadeh, Nathan Lee +1
We can encode a qubit in the energy levels of a quantum system. Relaxation and other dissipation processes lead to decay of the fidelity of this stored information. Is it possible…
Electric fields for light: Propagation of microwave photons along a synthetic dimension
Nathan R. A. Lee, Marek Pechal, E. Alex Wollack +3
The evenly-spaced modes of an electromagnetic resonator are coupled to each other by appropriate time-modulation, leading to dynamics analogous to those of particles hopping betwee…
Quantum dynamics of a few-photon parametric oscillator
Zhaoyou Wang, Marek Pechal, E. Alex Wollack +4
Modulating the frequency of a harmonic oscillator at nearly twice its natural frequency leads to amplification and self-oscillation. Above the oscillation threshold, the field sett…
