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...

Quantum Journal Club: Deterministically Encoding Quantum Information Using 100-P
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...

Quantum Journal Club: The Uncertainty Principle Determines the Nonlocality of Qu
内容： Two central concepts of quantum mechanics are Heisenberg’s uncertainty principle and a subtle form of nonlocality that Einstein famously called “spooky action at a distance.” These two funda...

Continuous-Variable Quantum Cryptography: Current Status and Future Directions
内容： Quantum cryptography allows two people to communicate in absolute secrecy using unbreakable codes. In this talk I introduce the basics of the continuous-variable version of quantum cryptography...
