solar cells<\/a> or even for high-temperature superconductors. However, achieving such feats is beyond even the capacity of the world’s most powerful supercomputers.<\/p>\nThe Fermi-Hubbard model is recognised as a leading benchmark for near-term quantum computers due to it being the simplest materials system that includes non-trivial correlations beyond what is attained by classical methods. Producing the lowest-energy (ground) state of the Fermi-Hubbard model allows the user to calculate the vital physical properties of the model.<\/p>\n
Pushing quantum computing to unprecedented levels<\/h3>\n Previously, experts have only managed to solve small, highly simplified Fermi-Hubbard instances on quantum computers. By leveraging a new, highly efficient algorithm and advanced error-mitigation techniques, they performed an experiment that was four times larger and contained ten times more quantum gates than anything previously recorded.<\/p>\n
Ashley Montanaro, Professor of Quantum Computation at the University of Bristol and Phasecraft co-founder, commented: “The Fermi-Hubbard instance in this experiment represents a crucial step towards solving realistic materials systems using a quantum computer.<\/p>\n
\u201cWe succeeded by developing the first truly scalable algorithm that anyone has managed to implement for the Fermi-Hubbard model. That’s particularly exciting because it suggests that we will be able to scale our methods in order to leverage more powerful quantum computers as the hardware improves.”<\/p>\n
Ryan Babbush, Head of Quantum Algorithms at Google AI, said: “We are delighted to see this experiment designed and executed by Phasecraft, representing one of the largest digital fermionic simulations to date, and also one of the largest variational algorithms to date, performed on Google’s quantum computing hardware. The scalability of their approach derives from being state-of-the-art in terms of both error-mitigation and algorithm compilation for near-term quantum hardware.”<\/p>\n
Stasja Stanisic, Senior Quantum Engineer at Phasecraft, the paper’s lead author, concluded: “This experiment represents a new milestone. It tells us what today’s quantum computers are capable of when we apply the best algorithmic technology available. We can build on this work to develop better algorithms and better encodings of realistic problems for today’s devices.”<\/p>\n","protected":false},"excerpt":{"rendered":"
