On March 18th, Chetan Nayak, a physicist leading Microsoft’s quantum team, presented new data on the company’s quantum computing chip at the American Physical Society’s Global Physics Summit in Anaheim, California. It was meant to calm a raging debate among physicists, but researchers remain skeptical of the results. “I never felt like there would be one moment when everyone is fully convinced,” Nayak told Nature in a March 18th article. The controversy centers on Microsoft’s February claim tha

In a scene from the movie Gladiator, Roman emperor Marcus Aurelius, worried about the fragility of his empire, tells his general, Maximus: “There was once a dream that was Rome. You could only whisper it. Anything more than a whisper and it would vanish.” The same could be said qubits. They are foundational components of quantum computers, and are one of thornier challenges in getting stable and usable systems up and running. A key reason is how fragile they are and how easily they can lose the

Amazon AWS Amazon Web Services is the third of the Big Three cloud computing giants to announce a quantum computing chip breakthrough this week, joining Microsoft last week and Google in December. Amazon's researchers claim their chip, Ocelot, can be much more efficient in using qubits, the fundamental building block of quantum computing, in an approach akin to traditional chip transistors. In a technical research article in this week's Nature magazine, lead author Harald Putterman of Amazon'

Amazon announced that it has created its own quantum computing chip, joining Microsoft and Google in a push to take this potentially transformative technology from the theoretical to the practical. Ocelot is a prototype that's intended to test the effectiveness of Amazon Web Services' quantum error correction architecture. Compared with other chip methods, the company claims Ocelot can reduce the cost of implementing quantum error correction by up to 90 percent. Quantum computing could solve co

Amazon is making its foray into quantum computing with the launch of a new chip designed to make quantum error correction more efficient. In an announcement on Thursday, Amazon Web Services (AWS) said the chip, called Ocelot, can “reduce the costs of implementing quantum error correction by up to 90%, compared to current approaches.” Quantum comput

Amazon Web Services has unveiled its Ocelot chip based on a hardware-efficient quantum computing architecture. Fernando Brandão and Oskar Painter of AWS said in a blog post that the pair of silicon microchips that compose the Ocelot logical-qubit memory chip represent the company’s first-generation quantum chip, and it could reduce the costs of implementing quantum error correction by up to 90%. Ocelot represents Amazon Web Services’ pioneering effort to develop, from the ground up, a hardware

Ocelot consists of nine quantum bits, or qubits, on a chip about a centimeter square, which, like some forms of quantum hardware, must be cryogenically cooled to near absolute zero in order to operate. Five of the nine qubits are a type of hardware that the field calls a “cat qubit,” named for Schrödinger’s cat, the famous 20th-century thought experiment in which an unseen cat in a box may be considered both dead and alive. Such a superposition of states is a key concept in quantum computing. T

Following up on Microsoft's announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two different types of qubit hardware to improve the stability of the quantum information they hold. The idea is that one type of qubit is resistant to errors, while the second can be used for implementing an error-correction code that catches the problems that do happen. While there have been more effe

Researchers at Microsoft have announced the creation of the first “topological qubits” in a device that stores information in an exotic state of matter, in what may be a significant breakthrough for quantum computing. At the same time, the researchers also published a paper in Nature and a “road map” for further work. The design of the Majorana 1 processor is supposed to fit up to a million qubits, which may be

Microsoft says its Majorana 1 contains eight topological qubits and can scale to a million, though the details on how it will scale are scant. Microsoft Quantum Microsoft's quantum computing scientists announced they have finally realized a long-held goal of building a "topological qubit", the equivalent of a transistor for ordinary chips, that may help advance quantum computing. The qubit is the functional element of a quantum chip, called Majorana 1, based on an exotic particle, a hybrid of

Q1. Did you see Microsoft’s announcement? A. Yes, thanks, you can stop emailing to ask! Microsoft’s Chetan Nayak was even kind enough to give me a personal briefing a few weeks ago. Yesterday I did a brief interview on this for the BBC’s World Business Report, and I also commented for MIT Technology Review. Q2. What is a topological qubit? A. It’s a special kind of qubit built using nonabelian anyons, which are excitations that can exist in a two-dimensional medium, behaving neither as fermio
