Spin-Charge Qubits in Bilayer Graphene–WSe₂ van der Waals Heterostructures
In a paper published in npj 2D Materials and Applications, we unveil a qubit platform built from bilayer graphene and WSe₂, showcasing strong spin–orbit coupling and gate operations on the picosecond timescale.
In our latest work, we describe a spin–charge qubit implemented in a bilayer graphene–WSe₂ van der Waals stack. First‑principles simulations reveal pronounced spin–orbit effects and control pulses lasting just a few picoseconds. This study was conducted as part of the Quantech Workshop for master’s students in the ETH Zurich Quantum Engineering program and was supervised by researchers in our group.
