... unfortunately: theoretically, the cosmos is awash with slow neutrinos, but they are too hard to detect. Although such a direct test of Majorana’s hypothesis seems out of reach for now, several ambitious experiments are underway to test one of its implications, namely, that even the last bastion of l ...

Secure Multi-party Quantum Computation
... in his possession; he does not need to know a classical description of it. Moreover, unlike in the classical case, we cannot assume without loss of generality that the result of the computation will be broadcast. Instead, each player in the protocol receives some part of the output. Informally, we r ...

Imaging single photons in non-separable states of polarization and spatial mode
... left circularly polarized, and with a relative phase of δ. Such a state is straight forward to produce say with an interferometer, and to visualize it classically as a coherent superposition.

Bohr`s quantum postulate and time in quantum mechanics
... In a nutshell, according to Bohr it is not possible to define a quantum system independently of the experimental context – (at least in part) classically described – that defines the conditions in which the quantum phenomenon is manifested. In this way it is not possible to take the wave function a ...

What the Humean Should Say About Entanglement
... The Humean is apparently, therefore, faced with the following problem. If she wants an adequate account of the physical world, she needs to take seriously entanglement phenomena, like the Singlet state, and the predictions associated with such phenomena. However, to do so she will have to admit that ...
