Quantum Machine Learning

... Since quantum systems produce counter-intuitive patterns believed not to be efficiently produced by classical systems, it is reasonable to postulate that quantum computers may outperform classical computers on machine learning tasks. The field of quantum machine learning explores how to devise and implement concrete quantum software that offers such advantages. Recent work has made clear that the hardware and software challenges are still considerable but has also opened paths towards solutions.

Аннотация статьи: 
Recent progress implies that a crossover between machine learning and quantum information processing benefits both fields. Traditional machine learning has dramatically improved the benchmarking and control of experimental quantum computing systems, including adaptive quantum phase estimation and designing quantum computing gates. On the other hand, quantum mechanics offers tantalizing prospects to enhance machine learning, ranging from reduced computational complexity to improved generalization performance. The most notable examples include quantum enhanced algorithms for principal component analysis, quantum support vector machines, and quantum Boltzmann machines. Progress has been rapid, fostered by demonstrations of midsized quantum optimizers which are predicted to soon outperform their classical counterparts. Further, we are witnessing the emergence of a physical theory pinpointing the fundamental and natural limitations of learning. Here we survey the cutting edge of this merger and list several open problems. 

Quantum computing, not AI, will define our future

... It’s been said that quantum computers will break current encryption schemes, kill blockchain, and serve other dark purposes.
If you want to get involved, check out the free tools that the household-name computing giants such as IBM and Google have made available, as well as the open-source offerings out there from giants and start-ups alike. Actual time on a quantum computer is available today, and access opportunities will only expand.
In keeping with my view that proprietary solutions will succumb to open-source, collaborative R&D and universal quantum computing value propositions, allow me to point out that several dozen start-ups in North America alone have jumped into the QC ecosystem along with governments and academia. Names such as Rigetti Computing, D-Wave Systems, 1Qbit Information Technologies, Inc., Quantum Circuits, Inc., QC Ware, Zapata Computing, Inc. may become well-known or they may become subsumed by bigger players, their burn rate – anything is possible in this nascent field.

You Experience the Quantum World Every Time You See, Touch, or Smell

Molecules of very different shapes can all smell the same, and molecules of similar shapes can smell very differently. There must be some other difference that the receptors are picking up on. That difference may lie in quantum physics.

Molecules all have a different vibrational frequency, depending on their mass, their bonds, and their structure. It's possible that our noses detect the differences in vibration between molecules, rather than just their shape. There's some evidence for this: A scientist in the 1990s compared the scents of two molecules with different shapes but identical molecular frequencies and found that they smelled exactly the same.


Quantum network to test unhackable communications


"This is the first time anyone has even planned to carry out a quantum network like this: a permanent, functioning quantum teleportation network at long distances in the United States," said Fermilab Deputy Director and Chief Research Officer Joe Lykken. "We want to demonstrate the enabling quantum technology. And we want to capitalize on our expertise to pave the way for others to create their own networks. Decades ago, building something like this would have been just a dream. But we're doing it now, and soon others will be able to."

What is a quantum computer? Explained with a simple example.

The goal of this article is to give you an accurate intuition of what a quantum computer is using a simple example.

This article will not require you to have prior knowledge of either quantum physics or computer science to be able to understand it.
