Abstract

We find that interactions of coherently-shaped free electrons with photons enable universal quantum computation and error correction with GKP qubits. The electron can entangle multiple GKP qubits, creating GHZ and cluster states.

We show that the coherent interaction between free electrons and photons can be used for universal control of continuous-variable photonic quantum states in the form of Gottesman-Kitaev-Preskill (GKP) qubits. Specifically, we find that electron energy combs enable nondestructive measurements of the photonic state and can induce arbitrary gates. Moreover, a single electron interacting with multiple photonic modes can create highly entangled states such as Greenberger-Horne-Zeilinger states and cluster states of GKPs.

We show how coherent modulation of free-electron wavefunctions can alter the quantum nature of the light they emit. We utilize this concept to create Schrödinger-cat and GKP states, which are sought-after for fault-tolerant quantum computation.

We propose a photonic architecture enabling the generation of GKP states from squeezed vacuum states. A 12.1dB threshold of cluster squeezing is achieved by encoding the resultant GKP states into a quantum error correction code.
