Researchers have mathematically confirmed the "hiding conjecture" for Gaussian boson sampling across any number of squeezed input modes, removing a critical theoretical barrier to proving quantum advantage. This validation strengthens the argument that simulating these specific photonic processes remains intractable for classical computers, advancing the path toward practical quantum computation with light.

Researchers Prove Conjecture Supporting GBS Quantum Advantage

Quantum ZeitgeistAugust 24, 20264 min read

Until now, proving the computational difficulty of simulating quantum systems required limiting assumptions about their complexity. This work removes those limitations by confirming a key property, the ‘hiding conjecture’, holds true regardless of the number of squeezed input modes employed in Gaussian boson sampling. Completing this proof strengthens arguments that this particular task may offer a viable path towards demonstrating practical quantum advantage over conventional computers.

A key step toward practical quantum computation has been confirmed with the demonstration of a long-standing theoretical claim about Gaussian boson sampling, a promising approach to building photonic quantum computers. The successful demonstration of the ‘hiding conjecture’ for any number of squeezed input modes strengthens arguments that this particular quantum task is exceptionally difficult for conventional computers to simulate. A mathematical principle relating to Gaussian boson sampling has definitively been proven; it reinforces claims…
