[Tu-A1-E-04] Gate-Modulated Transitions Between Co-Propagating Valley Edge Channels in Silicon

〇Gento Yamahata¹, Takase Shimizu¹ (1. Basic Research Labs, NTT, Inc. (Japan))

We investigate transitions between co-propagating edge channels in a silicon quantum Hall system. Strong mixing occurs between valley-resolved edge states and can be modulated by a gate voltage, suggesting electrical control of valley edge states for valley-based flying qubits.
