Fabrication of two-dimensional single fluxonium
test circuits show coherence performance among best known results
for superconducting qubits
D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing
systems, software, and services and the world’s first commercial
supplier of quantum computers, today announced notable progress in
its development of high coherence qubits, with results expected to
have a significant impact on its future quantum technologies.
D-Wave has designed, manufactured, and operated fluxonium qubits
that have demonstrated quantum properties that are comparable to
the best seen to date in scientific literature.
The fluxonium qubit, pioneered by Michel Devoret and his
colleagues at Yale University in 2009, has recently become an
attractive candidate for use in next-generation gate model quantum
computing architectures. Given the growing industry interest and
D-Wave’s expertise in building flux-like qubit quantum
technologies, the company explored the use of fluxonium in its own
technology development efforts. D-Wave has manufactured and tested
fluxonium qubits in a 2-dimensional circuit geometry. The measured
coherence properties, with relaxation times in excess of 100
microseconds, are comparable to the current state-of-the-art for
such qubits. In addition, the measured effective temperature of its
fluxonium, 18 millikelvin, is among the best that has been reported
in the scientific literature to date for superconducting
qubits.
“These results show that fluxonium is a viable candidate qubit
for D-Wave’s gate model quantum computing architectures. Moreover,
in doing this work we have learned that fluxonium can address some
of the known shortcomings of competing superconducting gate model
qubits,” said Mark Johnson, SVP of quantum technologies and systems
products at D-Wave. “We believe this will have a significant impact
on D-Wave’s hardware development and reinforces our technical
leadership by demonstrating that we can design, manufacture, and
operate high-coherence fluxonium qubits that are comparable to the
best in the world.”
