Starting today, members of the public will be able to run programs on IBM’s quantum processor. Users can access the device – which comprises five superconducting quantum bits (qubits) – via the US-based company’s “IBM Quantum Experience” website.
Described as a “cloud-enabled quantum computing platform”, IBM says that users will be able to run algorithms and experiments on IBM’s quantum processor, manipulate individual qubits, as well as access quantum-computing tutorials and simulations.

This morning I took Hong Kong’s metro to the City University of Hong Kong, where I met Ruiqin Zhang, who as well as being a solid-state physicist at the university is also president of the Physical Society of Hong Kong.

What will soon be the most expensive object on Earth? The answer, according to Greenpeace, is the Hinkley Point C nuclear power station that is slated for construction in south-west England. According to the BBC, the environmental group reckons the station will cost £24bn ($35bn) whereas EDF – the company that will build it – puts the construction cost at £18bn. In contrast, the Large Hadron Collider at CERN cost a mere £4bn. While the price tag on Hinkley Point C – which should produce 3.2 GW of electricity by 2024 – is eye watering, building a reactor on the cheap is not really an option.
Still, Hinkley Point C will not be the most expensive object ever built by humans. That honour goes to the International Space Station, which the BBC says cost nearly £78bn. There’s something comforting in knowing that the single highest expenditure ever has been on science – maybe civilization isn’t doomed after all.
Physics stretches from the small to the large, from the simple to the complex and from low energy to high. It spans the entire alphabet too, with this month’s issue of Physics World including everything from the race to produce anti-atoms (A) at the CERN particle-physics lab near Geneva to a study of the physics of zombies (Z).
Zombies don’t exist, obviously. But we look at two physicists – Alex Alemi and Matt Bierbaum – who have studied the statistical physics of how zombies spread. As science writer Stephen Ornes explains, their interest emerged from a fun student project, but has led to a paper in a leading peer-reviewed journal and helped generate a wider appreciation of statistical physics.
If you’re a member of the Institute of Physics (IOP), you can now enjoy immediate access to the new issue with the digital edition of the magazine in your web browser or on any iOS or Android mobile device (just download the Physics World app from the App Store or Google Play). If you’re not yet in the IOP, you can join as an IOPimember for just £15, €20 or $25 a year to get full access to Physics World digital.

Today is Earth Day, so let’s temporarily rename this regular Red Folder column as the Green Folder. Either way, today we’re going to focus on the Earth and environmental issues. The official website of Earth Day – an initiative now in its 46th year – has details about the various initiatives and events taking place around the world today.
First, let’s pay tribute to a physicist whose work had a profound influence on the climate and energy debate in the UK and beyond. Sir David Mackay died on 14 April aged 48 following a battle with cancer. Mackay is remembered among other things for his pragmatic approach to energy and his 2008 book Sustainable Energy: Without the Hot Air (free access) was hailed for its rigour and refreshing absence of rhetoric. Mackay’s writings attracted the interest of the British government who appointed him as chief scientific adviser to the Department of Energy and Climate Change in 2009, a post he held for five years. Ever prolific, Mackay was blogging about his experiences right up until two days before his death.
A blooming marvellous afternoon at the University of Utah.
By Hamish Johnston in Salt Lake City
Yesterday afternoon I hopped on a tram bound for the University of Utah. As you can see in the above photo, spring has sprung in Salt Lake City and the campus was resplendent in blossoms with views over snow-capped mountains.
I was at the university to film several 100 Second Science videos with Utah physicists including Shanti Deemyad, who studies the properties of matter under extremely high pressures. She is particularly interested in understanding the quantum properties of solids at temperatures near absolute zero – properties that can be enhanced when materials such as lithium are squeezed at pressures that are more than 10 million times greater than Earth’s atmosphere. This is done using a diamond anvil and Deemyad’s lab has 20 or so of them.

As Physics World editor, I spend most of my time covering science that I have never been involved in. I might write articles about astrophysicists, interview atomic physicists or edit features by particle physicists, but it doesn’t mean I’ve ever done any research in those fields.
It was therefore a pleasant change last Friday to attend a summit organized by the Institute of Physics, which publishes Physics World, on physics in food manufacturing. Back in the 1990s, I did a PhD with Athene Donald at the Cavendish Laboratory in Cambridge on the physical properties of mixtures of gel-forming biopolymers – materials that apart from being interesting from a fundamental point of view are also relevant to the food industry.
Many foods, after all, are complex, multicomponent mixtures – and if you can understand how they behave, then you can create foods that are healthier, cheaper and perhaps even tastier too.

I came to Salt Lake City hoping to glean a few golden nuggets of information about what future gravitational-wave detections we can expect from LIGO. What I found is that the collaboration is as tight-lipped as ever about discussing potential results. That’s fair enough and I understand the caution. However, I was hoping that the researchers would have loosened up a bit after their February announcement of the first gravitational-wave detection and share a little more with the general public.
