If you’ve ever attended the premiere of a film or an event where a new type of car is presented, you’ll know that there’s a slight buzz of excitement that comes from not knowing what to expect. I’ve been feeling that buzz for the past two weeks, leading up to an event that promised a “world premiere live demonstration of the next step in quantum cryptography”. It was not that the whole event was clouded in mystery, as some small teasers were released leading up to it. Still, with all the recent developments on the quantum Internet, I was left wondering: what exactly is the “state of the art” they plan to demonstrate? The event, which took place on Tuesday this week, was organized by a group of institutes and companies involved in quantum cryptography in the Netherlands. Amongst them were  QuTech , a collaboration of the Delft University of Technology and the Dutch Institute of Applied Scientific Research (TNO). Another was  Quantum Delta NL , a Dutch umbrella organization f

Imagine you sit down and pick up your favorite book. You look at the image on the front cover, run your fingers across the smooth book sleeve, and smell that familiar book smell as you flick through the pages. To you, the book is made up of a range of sensory appearances. But you also expect the book has its own independent existence behind those appearances. So when you put the book down on the coffee table and walk into the kitchen, or leave your house to go to work, you expect the book still looks, feels, and smells just as it did when you were holding it. Expecting objects to have their own independent existence – independent of us, and any other objects – is actually a deep-seated assumption we make about the world. This assumption has its origin in the scientific revolution of the 17th century and is part of what we call the  mechanistic worldview . According to this view, the world is like a giant clockwork machine whose parts are governed by set laws of motion. This

  Team develops simulator with 256 qubits, largest of its kind ever created. A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or “qubits.” Technology Harvard-MIT Quantum Computing Breakthrough – “We Are Entering a Completely New Part of the Quantum World” By  Harvard University  on  Jul 09, 2021 Team develops simulator with 256 qubits, largest of its kind ever created. A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or “qubits.” The system marks a major step toward building large-scale quantum machines that could be used to shed light on a host of complex quantum processes and eventually help bring about real-world breakthr
