Universal quantum computing with thermal state bosonic systems
Kevin Marshall, Daniel F. V. James, Alexandru Paler +1
Recent development of mixed-state encoding (MSE) allows pure-state logical information to be encoded by a bosonic (continuous-variable) system in mixed physical state. Despite inte…

Quantum-limited Euler angle measurements using anticoherent states
Aaron Z. Goldberg, Daniel F. V. James
Many protocols require precise rotation measurement. Here we present a general class of states that surpass the shot noise limit for measuring rotation around arbitrary axes. We th…
