Accelerating Sparse Linear Solvers with an Optical Laser Processing Unit
Dan Gluck, Yotam Mimran, Andrey Karenskih +4
Solving large, sparse linear systems is a fundamental workload in scientific computing and engineering simulations, often dominating runtime and energy consumption in high-performa…
Lightsolver challenges a leading deep learning solver for Max-2-SAT problems
Hod Wirzberger, Assaf Kalinski, Idan Meirzada +4
Maximum 2-satisfiability (MAX-2-SAT) is a type of combinatorial decision problem that is known to be NP-hard. In this paper, we compare LightSolver's quantum-inspired algorithm to…
Quantum Sparse Coding
Yaniv Romano, Harel Primack, Talya Vaknin +5
The ultimate goal of any sparse coding method is to accurately recover from a few noisy linear measurements, an unknown sparse vector. Unfortunately, this estimation problem is NP-…
LightSolver -- A New Quantum-inspired Solver Cracks the 3-Regular 3-XORSAT Challenge
Idan Meirzada, Assaf Kalinski, Dov Furman +5
The increasing complexity of required computational tasks alongside the inherent limitations in conventional computing calls for disruptive innovation. LightSolver devised a new qu…
Effect of ion-trap parameters on energy distributions of ultra-cold atom-ion mixtures
Meirav Pinkas, Ziv Meir, Tomas Sikorsky +3
The holy grail of ion-neutral systems is reaching the s-wave scattering regime. However, most of these systems have a fundamental lower collision energy limit which is higher than…
Strong angular-momentum mixing in ultracold atom-ion excitation-exchange
Ruti Ben-Shlomi, Romain Vexiau, Ziv Meir +5
Atom-ion interactions occur through the electric dipole which is induced by the ion on the neutral atom. In a Langevin collision, in which the atom and ion overcome the centrifugal…
Phase-locking between different partial-waves in atom-ion spin-exchange collisions
Tomas Sikorsky, Masato Morita, Ziv Meir +6
We present a joint experimental and theoretical study of spin dynamics of a single Sr ion colliding with an ultracold cloud of Rb atoms in various hyperfine states. Whil…
Direct observation of atom-ion non-equilibrium sympathetic cooling
Ziv Meir, Meirav Pinkas, Tomas Sikorsky +3
Sympathetic cooling is the process of energy exchange between a system and a colder bath. We investigate this fundamental process in an atom-ion experiment where the system is comp…
Spin controlled atom-ion inelastic collisions
Tomas Sikorsky, Ziv Meir, Ruti Ben-shlomi +2
The control of the ultracold collisions between neutral atoms is an extensive and successful field of study. The tools developed allow for ultracold chemical reactions to be manage…
Single-shot energy measurement of a single atom and the direct reconstruction of its energy distribution
Ziv Meir, Tomas Sikorsky, Nitzan Akerman +3
An ensemble of atoms in steady-state, whether in thermal equilibrium or not, has a well defined energy distribution. Since the energy of single atoms within the ensemble cannot be…
Experimental apparatus for overlapping a ground-state cooled ion with ultracold atoms
Ziv Meir, Tomas Sikorsky, Ruti Ben-shlomi +4
Experimental realizations of charged ions and neutral atoms in overlapping traps are gaining increasing interest due to their wide research application ranging from chemistry at th…
Doppler cooling thermometry of a multi-level ion in the presence of micromotion
Tomas Sikorsky, Ziv Meir, Nitzan Akerman +2
We study the time-dependent fluorescence of an initially hot, multi-level, single atomic ion trapped in a radio-frequency Paul trap during Doppler cooling. We have developed an ana…
Dynamics of a ground-state cooled ion colliding with ultra-cold atoms
Ziv Meir, Tomas Sikorsky, Ruti Ben-shlomi +3
Ultra-cold atom-ion mixtures are gaining increasing interest due to their potential applications in quantum chemistry, quantum computing and many-body physics. Here, we studied the…
