Coherent collective response in many-qubit systems for dark matter detection

Ryuichiro Kitano, Ryoto Takai

We propose an array of Ramsey-type interferometers using $N$ superposition states, $(∣0 ⟩ + ∣1 ⟩)^{\otimes N}$ , as a sensor to detect wave-like dark matter. Af…

Quantum sensing of high-frequency gravitational waves with ion crystals

Asuka Ito, Ryuichiro Kitano, Wakutaka Nakano +1

A detection method for high-frequency gravitational waves using two-dimensional ion crystals is investigated. Gravitational waves can resonantly excite the drumhead modes of the io…

Lepton number violating signals of a parity symmetric model at $I^¼$ TRISTAN

Keisuke Harigaya, Ryuichiro Kitano, Ryoto Takai

The parity solution to the strong CP problem necessarily extends the Standard Model to include the SU $(2)_{R}$ gauge sector and imposes restrictions on the structure of the Yuk…

Probing high-frequency gravitational waves with entangled vibrational qubits in linear Paul traps

Ryoto Takai

This work investigates the use of linear Paul traps as quantum sensors for detecting megahertz gravitational waves. Single-ion configurations exploit graviton-photon conversion in…

Higgs boson production at $I^¼^{+} I^¼^{+}$ colliders

Yu Hamada, Ryuichiro Kitano, Ryutaro Matsudo +4

We study Higgs boson production at $I^¼^{+} I^¼^{+}$ colliders at high energy. Since both initial-state particles are positively charged, there is no $W$ boson fusion at the leading orde…

Lepton flavor physics at $I^¼^{+} I^¼^{+}$ colliders

KÃ¥re Fridell, Ryuichiro Kitano, Ryoto Takai

We discuss sensitivities to lepton flavor violating (and conserving) interactions at future muon colliders, especially at $I^¼^{+} I^¼^{+}$ colliders. Compared with the searches for rare…
