Quantum Pulse Does Industrial Light Magic To Deliver Massive Boost In Qubits Israeli quantum startup Quantum Pulse Ventures has unwrapped a manufacturing line tweak that it says promises a ten times boost in quantum computer performance. The company unwrapped its QP2.0 platform at a conference in Edinburgh this week, and said its “composite pulse approach improves operational fidelity and robustness against fabrication variability.” The platform centers on a redesigned universal directional coupler that it claims delivers “an order-of-magnitude improvement in operational fidelity.” The company likens its directional coupler to a “transistor for optical computing, allowing two qubits to interact in a photonic circuit. Variations and inaccuracies in manufacturing of photonic circuits cause a cascade of problems that make errors more likely. This is one of the reasons that quantum computer designs must allow for a vast number of physical qubits and extensive error correction in order to deliver one logical qubit, meaning quantum computers, for now, are massive both in size and cost. Quantum Pulse’s design uses composite wave guides, rather than traditional one segment uniform wave guides, to reduce physical errors and noise in the circuits of these gates. The design is also more resistant to fabrication errors, it claims. The company said this can be used in a broad class of photonic integrated circuits. And it can be adopted across a range of current silicon photonics, silicon nitride, thin-film lithium niobate, and related integrated photonics manufacturing processes. Here are the components of its stack: Ofer Shapiro, co-founder and chief executive officer the Israeli company, said the coupler allowed light to jump from one wave guide to another, similar to a transistor in a traditional CMOS circuit. The wave guides themselves are “very, very small, they are less than one micrometer in size, and the distance between them has
