An accurate analog clock tick-tick-ticks with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy — 10 times as long corresp...
Quantum bit commitment has been known to be impossible by the independent proofs of Mayers, and Lo and Chau, under the assumption that the whole quantum states right before the unveiling phase are sta...
Entanglement enhanced bit rate over multiple uses of a lossy bosonic channel with memory
Entanglement enhanced bit rate multiple uses of a lossy bosonic channel memory
2010/4/12
We present a study of the achievable rates for classical information transmission via a lossy bosonic channel with memory, using homodyne detection. A comparison with the memoryless case shows that th...
