Quantum annealing of Cayley-tree Ising spins at small scales
Yunheung Song, Minhyuk Kim, Hansub Hwang +2
Significant efforts are being directed towards developing a quantum annealer capable of solving combinatorial optimization problems. The challenges are Hamiltonian programming and…
Quantum-Ising Hamiltonian programming in trio, quartet, and sextet qubit systems
Minhyuk Kim, Yunheung Song, Jaewan Kim +1
Rydberg-atom quantum simulators are of keen interest because of their possibilities towards high-dimensional qubit architectures. Here we report three-dimensional conformation spec…
Rydberg atom entanglements in the weak coupling regime
Hanlae Jo, Yunheung Song, Minhyuk Kim +1
We present an entanglement scheme for Rydberg atoms using the van der Waals interaction phase induced by Ramsey-type pulsed interactions. This scheme realizes not only controlled p…
Ultrafast time-scale Berry-phase gates of atomic clock states
Yunheung Song, Jongseok Lim, Jaewook Ahn
Extremely fast qubit controls can greatly reduce the calculation time in quantum computation, and potentially resolve the finite-time decoherence issues in many physical systems. H…
Coherent and dissipative dynamics of entangled few-body systems of Rydberg atoms
Woojun Lee, Minhyuk Kim, Hanlae Jo +2
Experimentally observed quantum few-body dynamics of neutral atoms excited to a Rydberg state are numerically analyzed with Lindblad master equation formalism. For this, up to five…
Rabi oscillations of Morris-Shore transformed -state systems by elliptically polarized ultrafast laser pulses
Hyosub Kim, Yunheung Song, Han-gyeol Lee +1
We present an experimental investigation of ultrafast-laser driven Rabi oscillations of atomic rubidium. Since the broadband spectrum of an ultrafast laser pulse simultaneously cou…
