With the advance of quantum technologies, new microscopy modalities are becoming possible – ones that can see electric currents, detect fluctuating magnetic fields, and even see single molecules on a surface. A prototype of such a microscope, demonstrating high resolution sensitivity, has been developed by an Australian research team.

While quantum computing seems like the big-ticket item among the developing technologies based on the behaviour of matter and energy on the atomic and subatomic level, another direction promises to open a new door for scientific research itself — quantum microscopy.

Researchers at Simon Fraser University have made a crucial breakthrough in the development of quantum technology.

Their research, published in Nature today, describes their observations of over 150,000 silicon ‘T centre’ photon-spin qubits, an important milestone that unlocks immediate opportunities to construct massively scalable quantum computers and the quantum internet that will connect them.

Quantum computing has enormous potential to provide computing power well beyond the capabilities of today’s supercomputers, which could enable advances in many other fields, including chemistry, materials science, medicine and cybersecurity.

In order to make this a reality, it is necessary to produce both stable, long-lived qubits that provide processing power, as well as the communi...

Researchers at the National Institute of Standards and Technology (NIST) have constructed and tested a system that allows commercial electronic components—such as microprocessors on circuit boards—to operate in close proximity with ultracold devices employed in quantum information processing. That design allows 4X as much data to be output for the same number of connected wires.

In the rising excitement about quantum computing, it can be easy to overlook the physical fact that the data produced by manipulation of quantum bits (qubit...
