内容: In this talk I present a theoretical study of calculating sub-Doppler forces for 137 Ba ions. The D1 transition line is employed for cooling line. Two cooling schemes are used: (i) Fg=1 - Fe=2 ...
内容: We propose an efficiently measurable lower bound on quantum process fidelity of N-qubit controlled-Z gates. This bound is determined by average output state fidelities for N partially conjugate...
内容: This paper studies verification of quantum systems, including quantum programs. We consider three kinds of long-term behaviour, namely reachability, repeated reachability and persistence, of qu...
内容: Controlling the interaction of a single quantum system with its environment is a fundamental challenge in quantum science and technology. We strongly suppressed the coupling of a single spin in...
内容: A fundamental feature of the quantum world that we live in is that (non-orthogonal) quantum states cannot be cloned. This no cloning theorem lies at the heart of quantum mechanics and is a dire...
内容: In contrast to a single quantum bit, an oscillator can store multiple excitations and coherences provided one has the ability to generate and manipulate complex multi-photon states. We demonstr...
