Dear Colleagues,

This Thursday, BME Department of Theoretical Physics hosts the following
seminar talk:

Bence Hetényi (Basel)
Hole-spin qubits in silicon and germanium

Location: seminar room of BME Department of Theoretical Physics, 1111
Budapest, Budafoki út 8.
Time: July 14 Thursday, 10:00 (sharp)

Abstract: "Leveraging the industry-standard fabrication techniques, spin
qubits in silicon and germanium quantum dots are amongst the most potent
platforms for scalable quantum computing. Hole-spin qubits come with the
benefit of a strong and highly tunable Rashba spin-orbit interaction,
providing a crucial overhead compared to their electronic counterparts. Even
though hole states resolve some of the key challenges of electron-spin
qubits, the strong spin-orbit interaction of holes comes at a price. In my
talk, I will consider the milestone experiments with hole-spin qubits and
present some of the recent theoretical proposals to overcome the
material-specific challenges. In particular, I will discuss qubit decoherence
due to charge noise, the anisotropy of the hole-spin exchange interaction and
how it influences the performance of two-qubit gates."

Best regards,
Andras Palyi
