With the help of opera singers and a speech-language pathologist, an MIT researcher helps develop first wearable device to quantify vocal fatigue.

Combining skin-interfaced sensors w/a haptic feedback module, the device can monitor singers' vocal health: https://t.co/bkM3t56BNP pic.twitter.com/5JLoleetcA

As this is scaled up, it has the potential to significantly broaden the range of problems to which quantum computers can be applied. Imagine a traditional computer that could only run computations of 20 computation steps, versus one that could run arbitrary length programs.

Scaling quantum error correction for longer computations

With further scaling, the error rates on "logical" qubits can hopefully be driven down sufficiently that we can run arbitrary-length quantum computations on a quantum computer, instead of ones with a limited number of steps.

Physical Qubits Combined Into Noise-Resistant Logical Qubits

What this work shows is that it is possible to group together many physical qubits and use all of their states to make a "logical" qubit, whose state is significantly less noisy (see the discussion in the blog post on surface codes, phase-flip errors and bit-flip errors).

Developing useful large-scale quantum computers will require qubits with much lower error rates. Our latest results, published in @Nature
, demonstrate a prototype of a logical qubit, a milestone on the path toward scalable fault-tolerant quantum computing: https://

Physical Qubits Noise Limits Quantum Computation Steps

The reason this is important is that single physical qubits are noisy, and on a computation running on physical qubits, this probability of noise accumulates over time, and therefore you are limited to running programs that are no more than a modest handful of computation steps.

Our @GoogleQuantumAI team has made an important step towards development of a large-scale quantum computer: building a prototype logical qubit & showing that quantum error correction makes that logical qubit better as it gets bigger. Congrats to the team! https://

En 1995, je découvre Internet. Mes profs en école de commerce : «ça ne marchera jamais». En 1998, je lance mon entreprise dans le web. Mon banquier : «ça ne marchera jamais». Et en 2023, un ministre du numérique compare une IA révolutionnaire à un perroquet. On est mal barrés.
