Blueprint for quantum computing using electrons on helium
Erika Kawakami, Jiabao Chen, Mónica Benito +1
We present a blueprint for building a fault-tolerant quantum computer using the spin states of electrons on the surface of liquid helium. We propose to use ferromagnetic micropilla…
Analytical formulation of the second-order derivative of energy for orbital-optimized variational quantum eigensolver: application to polarizability
Yuya O. Nakagawa, Jiabao Chen, Shotaro Sudo +2
We develop a quantum-classical hybrid algorithm to calculate the analytical second-order derivative of the energy for the orbital-optimized variational quantum eigensolver (OO-VQE)…
Qulacs: a fast and versatile quantum circuit simulator for research purpose
Yasunari Suzuki, Yoshiaki Kawase, Yuya Masumura +17
To explore the possibilities of a near-term intermediate-scale quantum algorithm and long-term fault-tolerant quantum computing, a fast and versatile quantum circuit simulator is n…
Strong coupling of two-dimensional electron ensemble to a single-mode cavity resonator
Jiabao Chen, Oleksiy Zadorozhko, Denis Konstantinov
We investigate the regime of strong coupling of an ensemble of two-dimensional electrons to a single-mode cavity resonator. In particular, we realized such a regime of light-matter…
Adiabatic preparation of squeezed states of oscillators and large spin systems coupled to a two-level system
Jiabao Chen, Denis Konstantinov, Klaus Mølmer
We study a single two-level system coupled resonantly to an oscillator mode or a large spin. By adiabatically turning on a linear driving term on the oscillator or the spin, the ei…
