Here in the 21st century, quantum computing is rapidly turning from a dream into a reality. But what is the hype, and what is actually true?
This illustration shows the widely available Rigetti quantum computer, Novera, which has 9 superconducting physical arms inside it. The big hope is that by scaling up to larger numbers of physical qubits, quantum advantage will be a milestone that can be achieved in the relatively near future.

While regular “classical” computers encode information in bits, where at the most fundamental level, binary states “0” and “1” control how calculations are performed, quantum computers are different.
-
They also allow for “mixed” states, where things are not just either “0” or “1”, but can be a simultaneous superposition of the two, allowing not only new states, but new operators as well.

Many people mistakenly believe that this means that quantum computers will one day replace classical computers, but this is very far from the truth. Stop the quantum computing hype and discover what's really real!
Happy New Year everyone, and with the new year comes an amazing new podcast! We usually cover a complex and underappreciated aspect of astrophysics on the podcast, but I had the opportunity to bring in a real expert in the field of quantum computing and I couldn't pass up the opportunity.
You've probably heard a lot of hype around quantum computers and the benefits they're expected to bring, with buzzwords like “P=NP”, “quantum supremacy” and “quantum advantage” thrown around, but a lot of what you're likely to hear is not Actual science. Good thing I was able to get it doctor. Riccardo Manenti as guest For our podcast!
Riccardo is the author of a cutting-edge textbook on quantum computers, holds a PhD from Oxford in quantum computing, and has been working at quantum computing startup Rigetti for several years. Join us K It helps demystify some recent progress and problems At the forefront of this promising new arena of physics, here on the Starts With A Bang podcast!
Since the James Webb Space Telescope first glimpsed the universe, we have entered a new era in understanding the oldest objects in the universe. what did we learn?
When we look at our Sun, its properties are incredibly constant, changing by only 0.1% over time. But all stars don't play by these rules.
Between the less massive star and the more massive planet lies the mysterious brown dwarf: a class of objects that are neither star nor planet.
The largest and brightest galaxies are the easiest to spot, but the smallest ones teach us how the Milky Way came together and came to be!
How scientists hear the 'hum' of the universe's gravitational background for the first time.
It can perform speech recognition tasks with up to 78% accuracy.
