One of the central concerns of computer science is how the resources needed to perform a
given computation depend on that computation. Moreover, one of the major resource …

Graph theory is now becoming a standard tool in system-level neuroscience. However,
endowing observed brain anatomy and dynamics with a complex network structure does not …

The Landauer principle states that any logically irreversible information processing must be
accompanied by dissipation into the environment. In this Letter, we investigate the heat …

We study the thermodynamic cost associated with the erasure of one bit of information over
a finite amount of time. We present a general framework for minimizing the average work …

The Landauer principle states that at least k BT ln 2 of energy is required to erase a 1-bit
memory, with k BT the thermal energy of the system. We study the effects of inertia on this …

We consider how the energy cost of bit reset scales with the time duration of the protocol. Bit
reset necessarily takes place in finite time, where there is an extra penalty on top of the …

We develop a physics-based model for classical computation based on autonomous
quantum thermal machines. These machines consist of few interacting quantum bits (qubits) …

In many real-world situations, there are constraints on the ways in which a physical system
can be manipulated. We investigate the entropy production (EP) and extractable work …

Digital computers implement computations using circuits, as do many naturally occurring
systems (eg, gene regulatory networks). The topology of any such circuit restricts which …

The fundamental energy cost of irreversible computing is given by the Landauer bound of k
T ln 2/bit, where k is the Boltzmann constant and T is the temperature in Kelvin. However …
