At the core of quantum computing is the qubit. The best ones have a few defining traits, and scientists are looking to everything from lasers to Russian diamonds to help refine the best qubits for the next generation of quantum computing.
When Gravity Breaks Down
Posted in quantum physics
Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. Most prior work in quantum computation deals with “qubits,” the quantum analogue of binary bits that encode either zero or one. The new work instead leverages “qutrits,” quantum analogues of three-level trits capable of representing zero, one or two.
The UChicago group worked alongside researchers based at Duke University. Both groups are part of the EPiQC (Enabling Practical-scale Quantum Computation) collaboration, an NSF Expedition in Computing. EPiQC’s interdisciplinary research spans from algorithm and software development to architecture and hardware design, with the ultimate goal of more quickly realizing the enormous potential of quantum computing for scientific discovery and computing innovation.

Understanding electrons’ intricate behavior has led to discoveries that transformed society, such as the revolution in computing made possible by the invention of the transistor.
The future is quantum, and while it’s absolutely full of possibilities, the increased power and scale of quantum computing presents some serious security concerns.
I’m Dr Janni Lloyd. My interest in health formally began in 1973 when I commenced my medical degree at the University of Western Australia. I spent many years in General Practice with a special interest in the psychological and emotional aspects of health maintenance and disease creation. In 1994 I moved into Holistic / Alternative / Complementary health. In 1992 I began studying Healthy Longevity / Indefinite Life Extension and the philosophy of Physical Immortality from many different perspectives – spirituality/theology, holistic health, psychology, medical science and quantum physics.
The following essay/article combines many of these different viewpoints.
HEALTHY LIFE EXTENSION / PHYSICAL IMMORTALITY – THE MASS POSSIBILITY
Breakthrough demonstrations using defective diamonds, high-flying drones, laser-bathed crystals and other exotica suggest practical, unhackable quantum networks are within reach.
