Episode 141: Chasing Fidelity with Mike Piech

In Episode 141, Mike Piech, Vice President of Business Development at Rigetti Computing, joins Patrick and Ciprian to talk hardware. Rigetti recently announced their 108-qubit system and is targeting 99.5% two-qubit gate fidelity by end of year, with a thousand physical qubits in sight by 2029. Mike breaks down why superconducting qubits are built on decades of semiconductor manufacturing know-how, what the Josephson junction actually does and why non-linearity is the key to isolating a usable qubit state, and why a macroscopic circuit behaving quantumly is one of the more remarkable phenomena in modern physics. The conversation also covers Rigetti's international work — including a 36-qubit system at the UK National Quantum Computing Centre and a new 108-qubit deployment in India with CDAC. The time to start learning quantum is now.
