New Class of Quantum Error-Correcting Codes for a Bosonic Mode
... matrix and independent of the logical words. The independence of entries αlk from the logical code words and the structure of the nondiagonal entries guarantee that the different errors are distinguishable and correctable. We consider a damped harmonic oscillator suffering from photon losses. Our in ...

The Role of Indistinguishability of Identical Particles in
... The subject of this thesis is the study of the concept of indistinguishability in quantum mechanics and, in connection with it, the use of particle statistics in quantum information processing. The first four chapters provide an overview of the thesis as well as an introduction to the basic principl ...

Three Roads To Quantum Gravity
... Heisenberg, Erwin SchroÈdinger, and many others. But this was only the starting point of the revolution, because neither of these two theories is complete enough to serve as a new foundation for physics. While very useful, and able to explain many things, each is incomplete and limited. Quantum theo ...

The fuzzball paradigm for black holes: FAQ
... about our theory of quantum gravity, we would traditionally accept the conditions (a) and (b) listed above as being natural. In that case we would be stuck with the paradox. We will see later that in string theory (a) is not true, so that it is possible for information to be encoded in the outgoing ...

Entanglement Entropy
... Let’s consider a quantum system: we usually identify it through its state, i.e. its wave function. In this way, we assume it is possible to define the system completely and build the function which represents it. However, this is not always feasible. For instance, in an electron-target scattering ex ...
