Quantum control of spin qubits using SOT-driven nanomagnets
Aniruddha Chakraborty, Kanishk Modi, Dhritiman Bhattacharya +3
Spin rotation (SR) is an essential capability for realization of single and two-qubit gates in spin quantum computing (SQC) architectures. To perform SR, resonant AC magnetic field…
Long-range electron-electron interactions in quantum dot systems and applications in quantum chemistry
Johannes Knörzer, Cornelis J. van Diepen, Tzu-Kan Hsiao +6
Long-range interactions play a key role in several phenomena of quantum physics and chemistry. To study these phenomena, analog quantum simulators provide an appealing alternative…
Quantum simulation of antiferromagnetic Heisenberg chain with gate-defined quantum dots
C. J. van Diepen, T. -K. Hsiao, U. Mukhopadhyay +3
Quantum-mechanical correlations of interacting fermions result in the emergence of exotic phases. Magnetic phases naturally arise in the Mott-insulator regime of the Fermi-Hubbard…
Mesoscopic Elastic Distortions in GaAs Quantum Dot Heterostructures
Anastasios Pateras, Joonkyu Park, Youngjun Ahn +9
Quantum devices formed in high-electron-mobility semiconductor heterostructures provide a route through which quantum mechanical effects can be exploited on length scales accessibl…
Ab Initio Exact Diagonalization Simulation of the Nagaoka Transition in Quantum Dots
Yao Wang, Juan Pablo Dehollain, Fang Liu +4
Recent progress of quantum simulators provides insight into the fundamental problems of strongly correlated systems. To adequately assess the accuracy of these simulators, the prec…
Nagaoka ferromagnetism observed in a quantum dot plaquette
Juan P. Dehollain, Uditendu Mukhopadhyay, Vincent P. Michal +7
Engineered, highly-controllable quantum systems hold promise as simulators of emergent physics beyond the capabilities of classical computers. An important problem in many-body phy…
Loading a quantum-dot based "Qubyte" register
C. Volk, A. M. J. Zwerver, U. Mukhopadhyay +8
Electrostatically defined quantum dot arrays offer a compelling platform for quantum computation and simulation. However, tuning up such arrays with existing techniques becomes imp…
A 2x2 quantum dot array with controllable inter-dot tunnel couplings
Uditendu Mukhopadhyay, Juan Pablo Dehollain, Christian Reichl +2
The interaction between electrons in arrays of electrostatically defined quantum dots is naturally described by a Fermi-Hubbard Hamiltonian. Moreover, the high degree of tunability…
A capacitance spectroscopy-based platform for realizing gate-defined electronic lattices
