- New UCSB research shows p-computers can solve spin-glass problems faster than quantum systems.
- Probabilistic computers (p-computers) built from probabilistic bits (p-bits) offer a practical alternative to quantum computers for hard optimization tasks.
- Two recent papers highlight the potential of p-computing, including synchronous and asynchronous architectures.
- A study demonstrated that a p-computer design outperformed a leading quantum annealer on spin-glass benchmarks.
- The research involved millions of p-bits and simulations to predict behavior at larger scales.
- Collaboration with chip designers showed that a 3 million-p-bit chip could be built with existing technology.
- The findings suggest that p-computers provide a scalable classical pathway for solving hard optimization problems, challenging the notion of quantum advantage.
