Arbitrarily Large Continuous-Variable Cluster States from a Single Quantum Nondemolition Gate
Arbitrarily Large Continuous-Variable Cluster States from a Single Quantum Nondemolition Gate
We present a compact experimental design for producing an arbitrarily large optical continuous-variable cluster state using just one single-mode vacuum squeezer and one quantum nondemolition gate. Generating the cluster state and computing with it happen simultaneously: more entangled modes become available as previous modes are measured, thereby making finite the …
