Quantum Journal Club: Ultrafast quantum random number generation based on quantu
内容： A quantum random number generator (QRNG) can generate true randomness by exploiting the fundamental indeterminism of quantum mechanics. Most approaches to QRNG employ single-photon detection te...

Soft Decoding of A Quantum Measurement Apparatus
内容： Quantum measurements are commonly performed by thresholding a collection of analog detector-output signals to obtain a sequence of single-shot bit values. The intrinsic irreversibility of the m...

Quantum Journal Club: Speed Optimized Two-Qubit Gates with Laser Coherent Contro
内容： We propose a new concept for a two-qubit gate operating on a pair of trapped ions based on laser coherent control techniques. The gate is insensitive to the temperature of the ions, works also ...

Quantum Journal Club: Quantum imaging with undetected photons
内容： Information is central to quantummechanics. In particular, quantum interference occurs only if there exists no information to distinguish between the superposed states. The mere possibility of ...

QUIC talk: Cryptographic Reversibility
内容： In this talk we consider the problem of cryptographic reversibility, which asks when a tripartite distribution PXYZ can be asymptotically distilled into secret key and diluted back into PXYZ us...

Relativistic quantum information: an overview and user's guide
内容： Information is physical, so the laws of physics impose the ultimate limits on the information processing. In fact, laws of quantum mechanics both limited and expanded the possibilities for comp...
