IBM researchers achieve 50 qubit quantum processor prototype

Volkswagen to work with Google on quantum computing projects

IBM has been offering quantum computing as a cloud service since previous year when it came out with a 5 qubit version of the advanced computers. A qubit is a single unit of quantum information.

"We at Volkswagen want to be among the first to use quantum computing for corporate processes as soon as this technology is commercially available". It will be available by the end of the year. This breakthrough puts IBM on the cutting edge of quantum computing research, as a 50-qubit machine is so far the largest and most powerful quantum computer ever built. Instead of being built on machines interpreting zeroes and ones in on/off states, quantum computers can live in multiple states. Recent additions to QISKit also include new functionality and visualization tools for studying the state of the quantum system, integration of QISKit with the IBM Data Science Experience, a compiler that maps desired experiments onto the available hardware, and worked examples of quantum applications. IBM Q, which was announced in March, is a followup to that effort.

Whereas normal computers store information as either a 1 or a 0, quantum computers exploit two phenomena-entanglement and superposition-to process information differently. A year later, they were up to 16 qubits. "IBM's team is fantastic and it's clear they're serious about this, but without looking at the details it's hard to comment", he says. "We have more qubits and less errors, which is combined to solve more problems", Gil said. In fact, IBM states its new quantum computer can hold a "quantum state" for 90 microseconds-an obviously short amount of time but a record for quantum computing. However, the 50-qubit version moves beyond that. While that doesn't sound like much, it's actually a huge leap forward.

Hartmut Neven, director of the Google Quantum Artificial Intelligence Laboratory, added: "Volkswagen has enormous expertise in solving important, real-world engineering problems". QISKit has been expanded so users can create and execute quantum computing programs on Q Systems.

GOOGLE HAS teamed up with entirely honest German vehicle maker Volkswagen to explore ways in which Google's quantum computing technology can be applied in the automotive sector. "Today, we are creating approximate universal, meaning it can perform arbitrary operations and programs, but it's approximating so that I have to live with errors and a [limited] window of time to perform the operations", Gil explained.

Besides the new processors, IBM is also updating its QISKit, which is an open-source software development kit meant for programming and running quantum computers that was released earlier this year.

Nonetheless, 50 qubits is a significant landmark in progress toward practical quantum computers. It is also trying to anticipate possible negative consequences of an advanced technology such as the ability to eventually be able to break encryption.
