This breakthrough, published in Nature Communications, introduces an optical phase modulator that is nearly 100 times thinner than a human hair.<\/p>\n<p>What makes this development particularly noteworthy is the manufacturing approach. Unlike previous quantum computing components that required custom-built laboratory equipment, this new device can be mass-produced using the same semiconductor fabrication processes used to manufacture microchips for smartphones, computers, and everyday electronics.<\/p>\n<p>The technology addresses one of the key challenges in quantum computing: controlling the precise laser frequencies needed to manipulate qubits. Traditional approaches require large, table-top devices that consume significant amounts of power and generate substantial heat. The new chip-based solution uses roughly 80 times less microwave power than existing commercial modulators.<\/p>\n<p>&#8220;You&#8217;re not going to build a quantum computer with 100,000 bulk electro-optic modulators sitting in a warehouse full of optical tables,&#8221; explained Professor Matt Eichenfield. &#8220;You need some much more scalable ways to manufacture them. If you can make them all fit on a few small microchips and produce 100 times less heat, you&#8217;re much more likely to make it work.&#8221;<\/p>\n<p>The team is now developing fully integrated photonic circuits that combine frequency generation, filtering, and pulse shaping on a single chip. Next, they plan to collaborate with quantum computing companies to test these chips in advanced quantum computers.<\/p>\n<p>This research was supported by the U.S. Department of Energy through the Quantum Systems Accelerator program.<\/p>","protected":false},"excerpt":{"rendered":"<p>Top-down image of the on-chip phase-modulator devices taken with a microscope.
