CRITICAL DYNAMICS OF THE ISING MODEL WITH ISING MACHINE

open access: yesLe Journal de Physique Colloques, 1988
The dynamical critical exponent z of he two-dimensional Ising model with sequential-flip heat-bath dynamics is numerically estimated to be 2.2, which agrees with that of Metropolis dynamics. The dedicated machine "m-TIS", designed and constructed by the present authors is used for the simulations.

A spinwave Ising machine

open access: yes, 2022
We demonstrate a spin-wave-based time-multiplexed Ising Machine (SWIM), implemented using a 5 $μ$m thick Yttrium Iron Garnet (YIG) film and off-the-shelf microwave components. The artificial Ising spins consist of 34--68 ns long 3.125 GHz spinwave RF pulses with their phase binarized using a phase-sensitive microwave amplifier.

Extractive Summarization on a CMOS Ising Machine

open access: yesIEEE Access
Extractive summarization (ES) aims to generate a concise summary by selecting a subset of sentences from a document while maximizing relevance and minimizing redundancy. Although modern ES systems achieve high accuracy using powerful neural models, their

Towards higher order oscillatory Ising machines [PDF]

open access: yesScientific Reports
Ising machines as hardware solvers of combinatorial optimization problems (COPs) can efficiently explore large solution spaces due to their inherent parallelism and physics-based dynamics. Many important COPs such as satisfiability (SAT) assume arbitrary

Gaussian optical Ising machines [PDF]

open access: yesPhysical Review A, 2017
It has recently been shown that optical parametric oscillator (OPO) Ising machines, consisting of coupled optical pulses circulating in a cavity with parametric gain, can be used to probabilistically find low-energy states of Ising spin systems. In this work, we study optical Ising machines that operate under simplified Gaussian dynamics.

Analog errors in Ising machines [PDF]

open access: yesQuantum Science and Technology, 2019
Abstract Recent technological breakthroughs have precipitated the availability of specialized devices that promise to solve NP-Hard problems faster than standard computers. These ‘Ising Machines’ are however analog in nature and as such inevitably have implementation errors.
