... discrete and continuous variables, such as energy and time (10), position and linear momentum (11), spatial modes (12, 13), and images (14). In addition to linear momentum, light may also carry angular momentum. The spin angular momentum is manifest as the polarization of light and is described comp ...

EXPONENTIAL SEPARATION OF QUANTUM AND CLASSICAL
... messages according to a shared protocol, until Bob has sufficient information to announce an output z ∈ Z s.t. (x, y, z) ∈ R. The communication cost of a protocol is the sum of the lengths of messages (in bits) Alice and Bob exchange on the worst-case choice of inputs x and y. The communication comp ...

Quantum mechanical modeling of the CNOT (XOR) gate
... 5. The symmetry considerations Here we pose the question of the symmetry group of the interaction eq. (27). A bit of care is required with this regard: whilst the states {|ii} of both the qubits can physically be virtually arbitrary (e.g., the ”ground”, |gi, and ”excited”, |ei) states, all the consi ...

Isotropic restriction in Group Field Theory condensates

In this synthesis the notions of space and time need to be deeply reshaped in order to take into account what we have learned from both quantum mechanics and GR. Background independenc ...

Quantum critical temperature of a modulated oscillator Lingzhen Guo, Vittorio Peano, M. Marthaler,
... The kink of the exponent of the probability distribution, i.e., of ln(ρn /ρn−1 ), is a singular modification of the distribution compared to the prediction of the conventional real-time instanton approach. Remarkably, it emerges where the perturbation formally remains small compared to the WKB param ...

In this respect, the assumption of finite precision of all physically realizable state preparation, manipulation, and registration procedures is particularly important, and can even be treated as an empirical given. This premise is general enough to subsume (a) fundamental limitations imposed by the ...

As Bell explained, “To avoid causal chains going backward in time in some frames of reference, we require them to go slower than light in any frame of reference.”7,8 After the advent o ...
