Compressed Quantum Operators and Roots of Hermite Polynomials
Serge Adonsou, Guillaume Dauphinais, David W. Kribs +1
The fundamental position and momentum operators of quantum mechanics are unbounded, but finite rank compressions of the operators can be considered to obtain partial information on…
Realistic Gottesman-Kitaev-Preskill stabilizer states enable universal quantum computation
Fariba Hosseinynejad, Pavithran Iyer, Guillaume Dauphinais +1
Physical Gottesman-Kitaev-Preskill (GKP) states are inherently noisy as ideal ones would require infinite energy. While this is typically considered as a deficiency to be actively…
Fault-tolerant logical measurements via homological measurement
Benjamin Ide, Manoj G. Gowda, Priya J. Nadkarni +1
We introduce homological measurement, a framework for measuring the logical Pauli operators encoded in CSS stabilizer codes. The framework is based on the algebraic description of…
Single-shot and measurement-based quantum error correction via fault complexes
Timo Hillmann, Guillaume Dauphinais, Ilan Tzitrin +1
Photonics provides a viable path to a scalable fault-tolerant quantum computer. The natural framework for this platform is measurement-based quantum computation, where fault-tolera…
Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer
J. Eli Bourassa, Rafael N. Alexander, Michael Vasmer +10
Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far…
Quantum Error Correction with the Semion Code
Guillaume Dauphinais, Laura Ortiz, Santiago Varona +1
We present a full quantum error correcting procedure with the semion code: an off-shell extension of the double semion model. We construct open strings operators that recover the q…
