Programmable non-Gaussian quantum light source with state and temporal-waveform tunability
Hiroko Tomoda, Yu Nishizawa, Akihiro Machinaga +7
A versatile quantum light source capable of programmably generating a variety of quantum light is a key enabler for photonic quantum technologies. In particular, independent contro…
Environment-Assisted Decoherence Suppression of Optical Non-Gaussian States
Akihiro Machinaga, Naoki Aritomi, Ryoga Sakurada +10
Optical loss is a common bottleneck in photonic quantum information processing, undermining the quantum advantage over classical approaches. Although several countermeasures, such…
Quantum-HPC hybrid computation of biomolecular excited-state energies
Kentaro Yamamoto, Riku Masui, Takahito Nakajima +16
We develop a workflow within the ONIOM framework and demonstrate it on the hybrid computing system consisting of the supercomputer Fugaku and the Quantinuum Reimei trapped-ion quan…
Profile control of fibre-based micro-mirrors using adaptive laser shooting with imaging
Shaobo Gao, Vishnu Kavungal, Shuma Oya +5
Fibre Fabry-Perot cavities (FFPCs) are used in various studies in cavity quantum electrodynamics (CQED) and quantum technologies due to the cavity's small mode volume and compact i…
Order-of-magnitude extension of qubit lifetimes with a decoherence-free subspace quantum error correction code
Shival Dasu, Ben Criger, Cameron Foltz +9
Constructing an efficient and robust quantum memory is central to the challenge of engineering feasible quantum computer architectures. Quantum error correction codes can solve thi…
Sequential and Programmable Squeezing Gates for Optical Non-Gaussian Input States
Takato Yoshida, Daichi Okuno, Takahiro Kashiwazaki +6
Quantum computing has been pursued with various hardware platforms, and an optical system is one of the most reasonable choices for large-scale computation. In the optical continuo…
