Characterization of Josephson Junction Aging and Annealing Under Different Environments
Rangga P. Budoyo, Rasanayagam S. Kajen, Bing Wen Cheah +2
Understanding the aging behavior of Josephson junctions and the effect of annealing on junction resistances is important in building large-scale superconducting quantum processors.…
Characterizing Noise in Controlling Superconducting Qubits
Yuanzheng Paul Tan, Yung Szen Yap, Long Hoang Nguyen +5
Meaningful quantum computing is currently bottlenecked by the error rates of current generation Noisy Intermediate Scale Quantum (NISQ) devices. To improve the fidelity of the quan…
Entanglement between superconducting qubits and a tardigrade
K. S. Lee, Y. P. Tan, L. H. Nguyen +8
Quantum and biological systems are seldom discussed together as they seemingly demand opposing conditions. Life is complex, "hot and wet" whereas quantum objects are small, cold an…
ICARUS-Q: Integrated Control and Readout Unit for Scalable Quantum Processors
Kun Hee Park, Yung Szen Yap, Yuanzheng Paul Tan +8
We present a control and measurement setup for superconducting qubits based on Xilinx 16-channel radio-frequency system-on-chip (RFSoC) device. The proposed setup consists of four…
Ghost factors in Gauss-sum factorization with transmon qubits
Lin Htoo Zaw, Yuanzheng Paul Tan, Long Hoang Nguyen +8
A challenge in the Gauss sums factorization scheme is the presence of ghost factors - non-factors that behave similarly to actual factors of an integer - which might lead to the mi…
Electron Spin Resonance with up to 20 Spin Sensitivity Measured using a Superconducting Flux Qubit
Rangga P. Budoyo, Kosuke Kakuyanagi, Hiraku Toida +2
We report on electron spin resonance spectroscopy measurements using a superconducting flux qubit with a sensing volume of 6 fl. The qubit is read out using a frequency-tunable Jos…
Electron Paramagnetic Resonance Spectroscopy of Er:YSiO Using Josephson Bifurcation Amplifier: Observation of Hyperfine and Quadrupole Structures
Rangga P. Budoyo, Kosuke Kakuyanagi, Hiraku Toida +4
We performed magnetic field and frequency tunable electron paramagnetic resonance spectroscopy of an Er doped YSiO crystal by observing the change in flux induced on…
