Landauer’s principle, formulated in 1961, postulates that irreversible logical or computational operations such as memory erasure require work, no matter how slowly they are performed. For example, to “reset to one” a one-bit memory requires at least kT ln2 of work, which is dissipated as heat. Bennett and, independently, Penrose later pointed out a link to Maxwell’s demon: Were Landauer’s...

The electronic and nuclear spins of shallow donor impurities in silicon have many highly attractive properties as qubits for a semiconductor-based quantum information technology. In addition to being compatible with standard CMOS processing, these qubits are atomically identical, have demonstrated incredibly long relaxation times, T1, and coherence times, T2, and a single-spin technology has...

We investigate the general open dynamics of a quantum system S undergoing a bombardment of short (unitary) interactions with an environment made of individual ancillas. We show how decoherence emerges from the fully unitary interaction of S with a large set of (in general non-identical) ancillas, and we compute the master equation that governs the dynamics of the system. Our findings may have...

We study the bipartite von Neumann and $\alpha =2$ Renyi entanglement
entropies for a system of free bosons put on a torus cut into two cylinders.
The torus is formed out of the $L\times L$ square lattice, and the
entropy is supposed to scale as $S = a L + c \gamma (L_A/L) + \cdots$, with
$L_A$ being the size of the partitioned region. $c$ and $a$ are some
constants and the function...
