A new paper from researchers at the University of Chicago introduces a technique for compiling highly optimized quantum instructions that can be executed on near-term hardware. This technique is particularly well suited to a new class of variational quantum algorithms, which are promising candidates for demonstrating useful quantum speedups. The new work was enabled by uniting ideas across the stack, spanning quantum algorithms, machine learning, compilers, and device physics. The interdisciplinary research was carried out by members of the EPiQC (Enabling Practical-scale Quantum Computation) collaboration, an NSF Expedition in Computing.

Adapting to a New Paradigm for Quantum Algorithms

The original vision for quantum algorithms dates to the early 1980s, when physicist Richard Feynman proposed performing molecular simulations using just thousands of noise-less qubits (quantum bits), a practically impossible task for traditional computers. Other algorithms developed in the 1990s and 2000s demonstrated that thousands of noise-less qubits would also offer dramatic speedups for problems such as database search, integer factoring, and matrix algebra. However, despite recent advances in quantum hardware, these algorithms are still decades away from scalable realizations, because current hardware features noisy qubits.

Researchers from Aalto University and VTT Technical Research Centre of Finland have built a super-sensitive bolometer, a type of thermal radiation detector. The new radiation detector, made of a gold-palladium mixture makes it easier to measure the strength of electromagnetic radiation in real time. Bolometers are used widely in thermal cameras in the construction industry and in satellites to measure cosmic radiation.

The new developments may help bolometers find their way to quantum computers. If the new radiation detector manages to function as well in space as it does in the laboratory, it can also be used to measure cosmic microwave background radiation in space more accurately.

“The new detector is extremely sensitive, and its noise level—how much the signal bounces around the correct value, is only one tenth of the noise of any other bolometer. It is also a hundred times faster than previous low-noise radiation detectors,” says Mikko Möttönen, who works as a joint Professor of Quantum Technology at Aalto University and VTT.

Researchers at EPFL have created a metallic microdevice in which they can define and tune patterns of superconductivity. Their discovery, which holds great promise for quantum technologies of the future, has just been published in Science.

In superconductors, electrons travel with no resistance. This phenomenon currently only occurs at very low temperatures. There are many practical applications, such as magnetic resonance imaging (MRI). Future technologies, however, will harness the total synchrony of electronic behavior in superconductors—a property called the phase. There is currently a race to build the world’s first quantum computer, which will use phases to perform calculations. Conventional superconductors are very robust and hard to influence, and the challenge is to find new materials in which the superconducting state can be easily manipulated in a device.

EPFL’s Laboratory of Quantum Materials (QMAT), headed by Philip Moll, has been working on a specific group of unconventional superconductors known as heavy fermion materials. The QMAT scientists, as part of a broad international collaboration between EPFL, the Max Planck Institute for Chemical Physics of Solids, the Los Alamos National Laboratory and Cornell University, made a surprising discovery about one of these materials, CeIrIn₅.

Brain Computer interface technology opens up a world of possibilities. We are on the cusp of this technology that is so powerful and has the potential to so radically transform our lives and existence! After starting three venture-funded startups in Silicon Valley, Steven Hoffman, known as Captial Hoff, launched Founders Space with the mission to educate and accelerate entrepreneurs and intrapreneur. Founder Space has become one of the top startup accelerators in the world with over 50 partners in 22 countries. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

TOKYO (Reuters) — Toyota Motor Corp (7203.T) unveiled a completely redesigned hydrogen-powered fuel cell sedan on Friday in its latest attempt to revive demand for the niche technology that it hopes will become mainstream.

Japan’s biggest automaker has been developing fuel-cell vehicles for more than two decades, but the technology has been eclipsed by the rapid rise of rival battery-powered electric vehicles promoted by the likes of Tesla Inc ( TSLA.O ).

Ahead of the Tokyo Motor Show starting on Oct. 24, Toyota unveiled a prototype of the new hydrogen sedan built on the same platform as its luxury Lexus brand’s LS coupe. The new Mirai model boasts longer driving range than its predecessor and completely redesigned fuel cell stack and hydrogen tanks, the company said.
