D-Wave Systems opened up free cloud access to its quantum computing resources for researchers responding to COVID-19. They're also enlisting their staff, partners, and customers to help others get up to speed on programming quantum computing for their specific tasks. By taking advantage of quantum weirdness – the ability of quantum bits (qubits) to exist in both a “one” and a “zero” state at the same time – these systems can potentially solve problems that cripple even the fastest of today’s supercomputers.

Since 2018, D-Wave has offered remote access to quantum computing via its “Leap” quantum cloud computing service. Baratz says an ecosystem of more than 1,000 developers has sprung up to apply Leap’s quantum computing resources to a variety of purposes, including protein folding and financial modeling, and optimizing public transportation routes in Lisbon, Portugal.
Then, in February, D-Wave began offering an enhanced quantum computing cloud service (Leap 2) which couples simulated qubits (on a conventional computer) with D-Wave’s actual qubits.
“We’ve seen problems being explored in the following areas: 1) the modeling and simulation of the spread of the virus, 2) the scheduling of nurses and other hospital resources, 3) assessing the rate of virus mutation, and 4) the assessment of existing drugs as potential treatments,” Baratz said. “We've heard positive feedback from organizations and developers around the world and are looking forward to their collaboration with our global partners to find potential solutions to COVID-19."

If quantum computing becomes practical, it will be able to crack encrypted data in an instant. Forbes has created a good two-minute video that gives a high level overview of quantum computation.
If you want to know more, Simon Singh's fantastic The Code Book gives a much more in-depth (yet still easy to understand) explanation of how quantum computing works. I can't recommend this book highly enough.
Jim Mortleman & Stuart Houghton write, "We're two UK tech journalists who also write comedy. This is our (UK-based) scripted comi-documentary podcast explaining the weird, wacky and potentially world-changing field of quantum computing to a curious but confused general audience. With laughs. In episode one we answer the question 'What the photonic muck is a quantum computer?' with the help of some of the world's leading quantum physicists and, er, Al Murray The Pub Landlord."
