The quantum industry in booming. An estimated $42bn was invested in the sector in 2023 and is projected to rise to $106 billion by 2040. In this episode of Physics World Stories, two experts from the quantum industry share their experiences, and give advice on how to enter this blossoming sector. Quantum technologies – including computing, communications and sensing – could vastly outperform today’s technology for certain applications, such as efficient and scalable artificial intelligence.

Our first guest is Matthew Hutchings, chief product officer and co-founder of SEEQC. Based in New York and with facilities in Europe, SEEQC is developing a digital quantum computing platform with a broad industrial market due to its combination of classical and quantum technologies. Hutchings speaks about the increasing need for engineering positions in a sector that to date has been dominated by workers with a PhD in quantum information science.

The second guest is Araceli Venegas-Gomez, founder and CEO of QURECA, which helps to train and recruit individuals, while also providing business development services. Venegas-Gomez’s journey into the sector began with her reading about quantum mechanics as a hobby while working in aerospace engineering. In launching QURECA, she realized there was an important gap to be filled between quantum information science and business – two communities that have tended to speak entirely different languages.

This episode of Physics World Stories explores the science, politics and ethics in the Netflix series 3 Body Problem. Adapted from the celebrated Chinese novel The Three-Body Problem by Liu Cixin, the multi-layered story centres around humanity’s first contact with an alien civilization. As the drama unfolds, with physicists among its lead protagonists, the plot navigates the challenges of communicating with aliens across interstellar space – and the inevitable tensions that arise on Earth.

To discuss 3 Body Problem, podcast host Andrew Glester is joined by three special guests:

• Matt Kenzie: the series’ science adviser, a particle physicist at the University of Cambridge. Kenzie’s role in informing the show’s scientific elements gives him unparalleled insight into the integration of physics into its narrative.
• Jennifer Ouellette: a renowned science writer who reviewed Cixin’s book The Three-Body Problem for Physics World back in 2015. Ouellette shares her thoughts on the book’s themes, and assesses the merits of the TV adaptation by the creators of Game of Thrones.
• Hannah Little: a linguist at the University of Liverpool who is also a member of the SETI Post-Detection Hub. That initiative, based at the University of St Andrews in Scotland, considers how we should communicate with aliens should we discover we are not alone in the cosmos.

This month’s episode of Physics World Stories features an interview with composer Amanda Lee Falkenberg with music from her The Moons Symphony. Her creation takes listeners on an epic journey through the science and stories of the moons of our solar system.

The seven-movement symphony dramatizes the geophysical features of Io, Europa, Titan, Enceladus, Miranda and Ganymede, before turning to our own Moon for a two-part finale. In creating the work, Australian-born Falkenberg immersed herself in the scientific research and consulted many scientists and astronauts.

The Moons Symphony performed by the London Symphony Orchestra is available now via Signum Records.

Coke or Pepsi? Messi or Ronaldo? Taylor Swift or…well, without wanting to set the Swifties against Physics World, let’s just say there’s often a tribal element to who we support or the choices we make.

In the world of cosmology, one heated divide is whether you’re for dark matter or modified Newtonian dynamics (MOND). Both theories attempt to explain the discrepancies between the predicted gravitational effects in the universe and some of the actual observed motions of stars and galaxies.

In the latest episode of Physics World Stories, Andrew Glester speaks to two cosmologists on opposing sides of this debate. Stacy McGaugh from Case Western Reserve University in the US is a former dark-matter researcher who switched sides overnight after MOND successfully predicted the rotation velocities of stars in galaxies.

The other guest, Indranil Banik from the University of St Andrews in the UK, took the opposite journey. While working on a six-year project to measure MOND in wide binaries, he found no deviation from standard Newtonian gravity at all – a hammer blow for MOND. Now a dark matter advocate, Banik cites observations in our own solar system as further evidence against MOND. Naturally, others disagree.
