Hidden qubit cluster states
Giacomo Pantaleoni, Ben Q. Baragiola, Nicolas C. Menicucci
Continuous-variable cluster states (CVCSs) can be supplemented with Gottesman-Kitaev-Preskill (GKP) states to form a hybrid cluster state with the power to execute universal, fault…
Subsystem analysis of continuous-variable resource states
Giacomo Pantaleoni, Ben Q. Baragiola, Nicolas C. Menicucci
Continuous-variable (CV) cluster states are a universal resource for fault-tolerant quantum computation when supplemented with the Gottesman-Kitaev-Preskill (GKP) bosonic code. We…
Modular Bosonic Subsystem Codes
Giacomo Pantaleoni, Ben Q. Baragiola, Nicolas C. Menicucci
We introduce a framework to decompose a bosonic mode into two virtual subsystems-a logical qubit and a gauge mode. This framework allows the entire toolkit of qubit-based quantum i…
All-Gaussian universality and fault tolerance with the Gottesman-Kitaev-Preskill code
Ben Q. Baragiola, Giacomo Pantaleoni, Rafael N. Alexander +2
The Gottesman-Kitaev-Preskill (GKP) encoding of a qubit within an oscillator is particularly appealing for fault-tolerant quantum computing with bosons because Gaussian operations…
