Abstract: We are now experiencing the second quantum revolution. After 20 years of extensive research, quantum technology has finally become mature enough to move to industrialization stage. One particular promising quantum technology is quantum computer, which harnesses quantum properties to dramatically enhance the efficiency of daunting computational tasks.
In this talk, I will specifically discuss the quantum computers that are made of bosonic systems, i.e. harmonic oscillators. Conventionally, building a bosonic quantum computer requires: 1) Cool the system to the ground state; 2) Specify two physical states as the encoding basis of a qubit; 3) Implement logic gates by engineering encoding-specific interaction. In our recent works, we show that all of these procedures are sufficient but not necessary. Specifically, we find a unified operation that can implement logic gates for any encoding. Such a "universal coupler" is regarded as a cornerstone of bosonic quantum computation, and is recently experimentally realized. Our formalism also permits a new class of encoding that a pure logical qubit is represented by a bosonic mode with arbitrary high thermal excitation. This new encoding relaxes the demanding requirement of ground-state cooling, and can better protect the quantum information against environmental noise. Additionally, I will discuss how our techniques can be applied in quantum machine learning.
