Quantum computers will revolutionize information technology, ushering in an era where certain types of calculations will be performed with almost unimaginable speed. Practical applications will include healthcare disciplines such as molecular biology and drug discovery; big data mining; financial services such as portfolio analysis and fraud detection; and artificial intelligence and machine learning.

The federal government is helping to create an environment in which quantum computing innovation and experimentation can flourish. The National Quantum Initiative Act puts $1.2 billion into the quantum research budgets of the Energy Department, the National Institute of Standards and Technology, NASA and the National Science Foundation. The law also outlines a 10-year plan to accelerate the development of quantum information science and technology applications.

Meanwhile, The White House’s Office of Science and Technology Policy is working to ensure that economic growth opportunities and opportunities for improving the world are baked into quantum policies and systems.

AI Mechanic Offers Solution for Tuning Quantum Computers

Posted by in categories: quantum physics, robotics/AI

The same concept applies to the processor integrated into a quantum computer, whose fragile bits should be tuned optimally before it can execute a calculation. But who would be the right mechanic to perform this quantum tune-up task?

According to a group that comprises researchers from the National Institute of Standards and Technology (NIST), the quantum tune-up job can be performed by artificial intelligence (AI).

Published in the Physical Review Applied journal, the researchers’ paper shows how an AI can be trained to make an interconnected set of modifications to minute quantum dots. These quantum dots are among the numerous potential devices used for developing the quantum bits, also known as qubits,” that would create the switches in the processor of a quantum computer.

Quantum internet may one day be possible through optical cavities, Caltech scientists say

Posted by in categories: computing, internet, particle physics, quantum physics

A fundamental challenge in the creation of a “quantum internet” is how to securely transmit data between two points. But one team of U.S. scientists may have found the answer.

New research from experts at the California Institute of Technology (Caltech) suggests atoms in small boxes of light — optical cavities — could soon “form the backbone technology” of the futuristic internet that relies on the mysterious properties of quantum mechanics for ultra-fast computing.

D-Wave Opens Quantum-Computing Resources to Coronavirus Research

Posted by in categories: biotech/medical, business, quantum physics, robotics/AI, supercomputing

Quantum-computing vendor D-Wave Systems Inc. said Tuesday it is giving researchers and companies studying the novel coronavirus free access to its early-stage, experimental machines over the cloud.

Canadian firm D-Wave is among several technology companies providing free advanced computing resources to researchers working to combat the global pandemic. International Business Machines Corp., for example, in March started offering free remote access to two of the world’s most powerful supercomputers.

D-Wave has assembled a team of experts from about a dozen universities and companies including Volkswagen AG, Denso Corp. and startup Menten AI who are familiar with its quantum-computing services to help interested researchers program the computers.

IBM, NUS tie up to tap quantum computing for problem solving

Posted by in categories: cybercrime/malcode, finance, quantum physics

Computing giant IBM and the National University of Singapore (NUS) have embarked on a three-year collaboration to find ways to use quantum computing to solve real-world problems and train quantum scientists.

Quantum computers are currently used in many areas, including medical research into new drug development and the enhancement of cyber security in the financial sector.

The collaboration between IBM and NUS, announced yesterday, is the first of its kind in South-east Asia and gives NUS researchers access to 15 of IBM’s powerful quantum computing systems via a cloud service.

Israel Aerospace Industries works with startups developing quantum technology

Posted by in categories: quantum physics, robotics/AI

Quantum computing, for its parts, replaces the traditional 1 and 0 computer binary system with a system that calculates the chances of 1 and 0—meaning that it could have both 1 and 0 at the same time, but with different probabilities. “This enables the computing of certain aspects far faster and in a more efficient manner. The computing time could be 1,000 or 10,000 times faster,” said Lupa. When combined with artificial intelligence, machines could learn on their own with the speed of quantum computing, he stated.

At the moment, only massive quantum computers exist, while quantum communications are still at the proof of concept stage. Quantum radars have made some progress. But all of this is expected to change.

“In the end, it will be a revolution,” said Lupa. “But it will not happen tomorrow. When these things become accessible to everyone, then it will be revolutionary.”

Tiny optical cavity could make quantum networks possible

Posted by in categories: computing, encryption, internet, quantum physics

Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature.

Quantum networks would connect quantum computers through a system that also operates at a quantum, rather than classical, level. In theory, quantum computers will one day be able to perform certain functions faster than by taking advantage of the special properties of quantum mechanics, including superposition, which allows to store information as a 1 and a 0 simultaneously.

As they can with classical computers, engineers would like to be able to connect multiple quantum computers to share data and work together—creating a “quantum internet.” This would open the door to several applications, including solving computations that are too large to be handled by a single quantum computer and establishing unbreakably secure communications using quantum cryptography.

Physicists develop new photon source for tap-proof communication

Posted by in categories: encryption, quantum physics, space

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.

A 15-member research team from the U.K., Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of 2.1 micrometers. In practice, entangled photons are used in encryption methods such as quantum key distribution to completely secure telecommunications between two partners against eavesdropping attempts. The research results are presented to the public for the first time in the current issue of Science Advances.

It has been regarded as technically possible to implement encryption mechanisms with entangled photons in the near-infrared range of 700 to 1550 nanometers. However, these have disadvantages, especially in satellite-based communication. They are disturbed by light-absorbing gases in the atmosphere as well as the background radiation of the sun. With existing technology, end-to-end encryption of transmitted data can only be guaranteed at night, but not on sunny and cloudy days.
