Quantum Journal Club: Efficient Experimental Estimation of Fidelity of Linear Op
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...

Quantum Journal Club: Microwave quantum logic gates for trapped ions
内容： Control over physical systems at the quantum level is important in fields as diverse as metrology, information processing, simulation and chemistry. For trapped atomic ions, the quantized motio...

Entanglement in Fermionic Quantum Theory
内容： We review the framework of operational probabilistic theories, with particular emphasis on those notions that are related to the structure of composite systems. We then introduce the fermion al...

Foundations of Quantum Field Theory in the light of Quantum Information: The Dir
内容： The experience in Quantum Information has led the community to look at foundations of Quantum Theory under a completely new angle, regarding the theory as a “theory of information”, and leadi...

Measurement-based noiseless linear amplification for entanglement distillation a
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...

Is the wave function in one-to-one correspondence with reality?
内容： The old question (considered already by Einstein) whether the quantum-mechanical wave function represents "reality" has recently attracted renewed interest. Amazingly, modern approaches inspire...
