On July 29, Xanadu, a Canadian firm in photonic (mild particle) quantum computing, introduced its latest breakthrough in partnership with HyperLight Company to develop photonic chips utilizing thin-film lithium niobate (TFLN).
“Our long-standing collaboration with HyperLight has been instrumental in attaining our {hardware} roadmap,” mentioned Zachary Vernon, CTO of {hardware} at Xanadu.
Via the mixed efforts of each firms, a brand new chip was created that demonstrated waveguide losses of solely 2dB/m, which means that the quantity of sunshine misplaced because it makes use of waveguides to journey by means of the chip has been dramatically diminished. Moreover, the switches that direct the place the sunshine goes within the chip demonstrated a lack of solely 20mdB of sunshine, one of many lowest recorded values of sunshine loss for this type of swap. Info can now journey by means of the chip with a lot much less interference.
“The unprecedented efficiency we’ve achieved with these new photonic chips units a brand new benchmark for efficiency within the trade and brings us nearer to delivering utility-scale photonic quantum computer systems,” mentioned Vernon.
This new chip was manufactured in a high-volume fabrication plant (fab). Because of this this groundbreaking chip, which is setting new benchmarks in efficiency, will be simply scaled up and prepped for business manufacturing, which shall be essential for overcoming present limitations that forestall photonic quantum computer systems from rising in scale.
