Quantum physics is the strange and counterintuitive theory of physics governing the tiny world of atoms, electrons and photons. To access such small and ephemeral phenomena, scientists deploy advanced techniques to isolate and manipulate what can be destroyed by the tiniest breeze. Can they further protect these phenomena and make them survive to reach the scale of our life? This will be required to build a functional quantum computer.

It’s that time of the year again: the Easter Bunny comes by and hides his eggs. Everywhere you look he hid them: in the flower beds in the garden, underneath your bed, even if you open the cupboards, eggs come rolling out. Eggs in all kinds of clear colours and, if you’re lucky, made of chocolate.
But, over the past year, the Easter Bunny spent his time studying some quantum mechanics. He was inspired and decided to do something totally different this year. Instead of eggs, he hid some quantum terminology in the puzzle below. Can you find all the quantum eggs he hid?
 This puzzle was made at WoordZoekerMaken.nl.
 The second ‘l’ in millikelvin got lost during the hiding…
Autumn (or Spring for our readers in the Southern hemisphere) is a time of change, and things are changing as well for Bits of Quantum. Editorial duties on this blog are performed on a volunteer basis by PhD students (in what little remains of their free time), and this means that any editor’s tenure is inherently limited by his or hers PhD track. This is why, with some sadness, we announce the departure of James and Suzanne, who have handed in their editorial powers to finish up their doctoral track. They were great members of the team and we would like to thank them for the time they have spent making this blog an amazing place for quantum computing.
Luckily change also brings renewal and we are very happy to announce that Bits Of Quantum has two new editors: Guan and Anne-Marije. They have been unofficially part of the team for a while now and we figured it was high time to formalize their editor-ship. Continue reading Farewell, Editors Emeriti; Welcome, New Editors
The phone was ringing in the lab, Sophie let it ring a few times before looking up from her experiment. She was a bit annoyed until she realized what time it was, almost midnight and she had only just got the experiment running. She picked up the phone, half expecting to hear her advisor when she heard her mother’s voice:
“Sophie, we were worried about you, you didn’t pick up your phone and it has been almost four hours!”.
“Don’t worry Mom, I’ll be right there, I just have to set up a measurement run overnight, otherwise the experiment will be doing nothing over Christmas!”
“But dear, like you said, it’s Christmas, you promised you’d be here! You know how Granny has been looking forward to seeing you.”
“OK, OK I’ll just start what I have now, but I still have to refill the traps. I’ll be there in 10 minutes”, she said as she hung up the phone.
As the nitrogen traps overflowed, a haze covered the floor and she started to feel a bit dizzy…
Welcome to ‘Bits Of Quantum’, the official blog by QuTech! QuTech is an academic research institution that houses many scientists who spend a large part of their time doing mathematics, experiments, and a lot of quantum mechanics. We would like to share bits of our quantum research with you, and give you a taste of what life in a large research institute is like. To that end we, four PhD students from different parts of QuTech, started the blog you are looking at right now. As the editorial team we are very excited about channeling all the stories that can be told by and about QuTech and quantum technologies. Thank you for reading this blog and we hope you enjoy reading the many posts to come!
The editorial team, Jonas, James, Adriaan and Suzanne
Jonas Helsen – Hey! My name is Jonas and I am one of the theorists at QuTech. I only started my PhD a year ago so I still have lots to learn but I’m really excited about being here! I’m also passionate about teaching people about the magical world of quantum computing which is why I co-started Bits Of Quantum with my lovely co-editors! Happy reading!
James Kroll – I am James, an experimental physicist hailing from Scotland. I work in the topological quantum computing roadmap of Leo Kouwenhoven, as it requires an exciting mix of condensed matter physics theory, experimental cryogenics, electrical engineering and computer programming – all things that I somehow enjoy. If I’m not in the lab, you will most likely find me cycling somewhere or reading. Or eating. That’s a pretty important part of my life.
Adriaan Rol – Hi, I am Adriaan, an experimentalist in Leo DiCarlo’s group where we are working on a quantum computer based on superconducting transmon qubits.
I really enjoy trying to find the (abstract) essence of things while at the same time being able to experimentally test if my ideas actually work.
Whenever I’m not in the lab you’ll probably find me on the water or enjoying an overpriced coffee at my favourite coffee place.
Suzanne van Dam – My name is Suzanne, and I am doing a PhD in the lab of Ronald Hanson, since two years now. One of my favourite things is to see the quantum world in the lab on a daily basis. My hope is that from this blog it will become clear why I am so excited about this!
