... 1. Since there is no signal photon in the public channel, it is extremely difficult for Eve to obtain any information. 2. Eve can copy Alice’s setup (so her photon is also “invisible”) and emits her photon into the channel to detect what Bob’s messages are. Fortunately, this attack can be avoided by ...

Strong-Disorder Fixed Point in the Dissipative Random Transverse-Field Ising Model
... The presence of quenched disorder in a quantum mechanical system may have drastic effects, in particular, close to and at a quantum critical point. The appearance of Griffiths-McCoy singularities [1,2], leading to the divergence of various quantities like the susceptibility at zero temperature even ...

1 Engineering Entanglement: Quantum Computation, Quantum
... Very few issues in the history of quantum mechanics have undergone so many twists as entanglement. According to the received view, the idea of entanglement was proposed as a paradox to challenge quantum mechanics. Albert Einstein, the major opponent of the Copenhagen interpretation, disagreed with W ...

No matter how far electron and positron are apart, the measurement on one particle has an instantaneous (i.e. faster-thanlight) effect on the other. It was this, in Einstein’s words, “spooky action at a distance” that ...
