Launching QUANTUM: The Exhibition

On August 30, Martin Laforest wrote a blog post about how to create a 4,000 square foot museum exhibition about an invisible science. That exhibition, QUANTUM: The Exhibition, came to life at THEMUSEUM for an invitation-only premiere on October 13, 2016 and then for the general public the next day.

Alumna Sarah Sheldon on the IBM Quantum Experience

On Tuesday, June 7, 24 students attending the Undergraduate School on Experimental Quantum Information Processing (USEQIP) at the Institute for Quantum Computing (IQC) used the IBM Quantum Experience to test algorithms that they were learning about in the classroom. Former IQC  PhD student, Dr. Sarah Sheldon, now a research staff member at the IBM T.J. Watson Research Center, introduced the students to the platform, assisted them in working through examples and described the inner workings of IBM’s quantum processor.

Specialized Quantum Computing

Attendees of the Semi-Quantum Computing workshop in 2016

On August 16-17 we organized (the first1) workshop on Semi-Quantum computing. It was a chance to discuss different approaches towards the first demonstration of a real quantum computational advantage. The approaches are seemingly very different, but many open challenges turn out to be similar.

Before we begin, HAVE YOU WATCHED THE VIDEO “ANYONE CAN QUANTUM”??? Paul Rudd, Keanu Reeves, Stephen Hawking, Quantum Chess, Quantum Physics for Babies, and even tardigrades: this video has it all!

Detecting Gravitational Waves. Can Quantum Mechanics Help?

Massive bodies warp spacetime

Secrets can be very hard to keep. The thought of having to wait five months to be able to talk about what is arguably the biggest scientific discovery in a century is incomprehensible. But for every member of the LIGO Scientific Collaboration (LSC), it was absolutely essential that nobody let the cat out the bag (or should that be box?).

Quantum Computational Intelligence

Imagine solving mathematical problems where you could use the full physical range of computational possibilities within the laws of the universe, and be inspired by the sublime algorithmic intelligence of the human brain. This is precisely why the emerging field of quantum machine learning (QML) has received so much recent attention. In this blog post, we’d like to discuss the fundamental ideas and applied value of machine learning to computation in general, and then contextualize these ideas in a new way within the paradigm of quantum computation.

Tomaytos, Tomahtos and Non-local Measurements

A projective measurement of an observable A

One of my discoveries as a physicist was that, despite all attempts at clarity, we still have different meanings for the same words and use different words to refer the the same thing. When Alice says measurement, Bob hears a `quantum to classical channel', but Alice, a hard-core Everettian, does not even believe such channels exist. When Charlie says non-local, he means Bell non-local, but string theorist Dan starts lecturing him about non-local Lagrangian terms and violations of causality. And when I say non-local measurements, you hear ????

QIP 2016

Elk in the winter

Quantum Information Processing (QIP) is a conference held each year about quantum computation and quantum information that brings out a large portion of the quantum computing community. The QIP conference started in 1998, and has continued annually. QIP 2016 marks the 19th gathering of scientists and researchers from around the world to join together and discuss various aspects of this specialized field.

Ask not for which local-hidden-variable-theory the Bell tolls. It tolls for all.

It looks like 2015 is the year of the loophole-free Bell test. Three different papers, with three very different p-values, all claim to put the final nail in the local-realistic coffin. I will compare the designs and results of the three experiments with an eye towards their strengths and weaknesses.[1] The three papers are, in order of experiment completion:
