Quantum Computation of Frequency-Domain Molecular Response Properties Using a Three-Qubit iToffoli Gate
Shi-Ning Sun, Brian Marinelli, Jin Ming Koh +7
The quantum computation of molecular response properties on near-term quantum hardware is a topic of significant interest. While computing time-domain response properties is in pri…
Programmable Heisenberg interactions between Floquet qubits
Long B. Nguyen, Yosep Kim, Akel Hashim +9
The fundamental trade-off between robustness and tunability is a central challenge in the pursuit of quantum simulation and fault-tolerant quantum computation. In particular, many…
Effects of Laser-Annealing on Fixed-Frequency Superconducting Qubits
Hyunseong Kim, Christian Jünger, Alexis Morvan +10
As superconducting quantum processors increase in complexity, techniques to overcome constraints on frequency crowding are needed. The recently developed method of laser-annealing…
Scalable High-Performance Fluxonium Quantum Processor
Long B. Nguyen, Gerwin Koolstra, Yosep Kim +12
The technological development of hardware heading toward universal fault-tolerant quantum computation requires a large-scale processing unit with high performance. While fluxonium…
Heisenberg-limited metrology via weak-value amplification without using entangled resources
Yosep Kim, Seung-Yeun Yoo, Yoon-Ho Kim
Weak-value amplification (WVA) provides a way for amplified detection of a tiny physical signal at the expense of a lower detection probability. Despite this trade-off, due to its…
High-fidelity three-qubit iToffoli gate for fixed-frequency superconducting qubits
Yosep Kim, Alexis Morvan, Long B. Nguyen +6
The development of noisy intermediate-scale quantum (NISQ) devices has extended the scope of executable quantum circuits with high-fidelity single- and two-qubit gates. Equipping N…
Benchmarking quantum tomography completeness and fidelity with machine learning
Yong Siah Teo, Seongwook Shin, Hyunseok Jeong +8
We train convolutional neural networks to predict whether or not a set of measurements is informationally complete to uniquely reconstruct any given quantum state with no prior inf…
Dispersion cancellation in a quantum interferometer with independent single photons
Dong-Gil Im, Yosep Kim, Yoon-Ho Kim
A key technique to perform a proper quantum information processing is to get a high visibility quantum interference between independent single photons. One of the crucial elements…
Universal compressive characterization of quantum dynamics
Yosep Kim, Yong Siah Teo, Daekun Ahn +6
Recent quantum technologies utilize complex multidimensional processes that govern the dynamics of quantum systems. We develop an adaptive diagonal-element-probing compression tech…
Observing the "quantum Cheshire cat" effect with noninvasive weak measurement
Yosep Kim, Dong-Gil Im, Yong-Su Kim +4
One of the common conceptions of nature, typically derived from the experiences with classical systems, is that attributes of the matter coexist with the substance. In the quantum…
Observation of second-order temporal interference with thermal light: Interference beyond the coherence time
Yong Sup Ihn, Yosep Kim, Vincenzo Tamma +1
We report observation of a counter-intuitive phenomenon in multi-path correlation interferometry with thermal light. The intensity correlation between the outputs of two unbalanced…
