Our 20-qubit machine has double the coherence time, at an average of 90 µs, compared to previous generations of quantum processors with an average of 50 µs.
In addition to that news, the company has also said that it will make a 20-qubit processor available for "client use and expanded developer tools" as a cloud computing solution for businesses and science later this year.
IBM said the 50-qubit processor will be implemented in Q Systems sometime next year via a series of planned upgrades, leading to even greater performance.
The latest advances are the result of three generations of development. Within just 18 months, the company brought online 5 and 16 qubit systems which clients can use to explore practical applications.
Aside from their 50-qubit machine, IBM also has a 20-qubit quantum computing system that's accessible to third-party users through their cloud computing platform. No word yet on when it'll come online.
Over the next year, IBM Q scientists will continue to work to improve its devices including the quality of qubits, circuit connectivity, and error rates of operations to increase the depth for running quantum algorithms.
The other issue that comes into play when dealing with quantum states is that they tend to exist for a short period of time in a process known as coherence.
"Being able to work on IBM's quantum hardware and have access through an open source platform like QISKit has been crucial in helping us to understand what algorithms-and real-world use cases-might be viable to run on near-term processors", said Matt Johnson, CEO, QC Ware. "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. A Jupyter notebook that can be used to repeat the experiments that led to this quantum chemistry breakthrough is available in the QISKit tutorials. IBM pointed out that quantum computing will have the ability to solve complex problems including chemical simulations and types of optimization.
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. Because they use qubits, quantum computers can manipulate multiple combinations of states at once, which makes them far more powerful than their nonquantum cousins, at least for performing a range of advanced computing tasks such as genomic sequencing, materials science research and more.
These quantum advances are being presented today at the IEEE Industry Summit on the Future Of Computing as part of IEEE Rebooting Computing Week.
