In a new episode of The Quantum Kid, Institute for Advanced Study physicist Juan Maldacena explains the holographic principle—the notion that all phenomena inside a spatial region, including gravity, can be encoded on its boundary. He quantifies the computational load required to model such a universe, stating that a quantum computer would need a large number of error‑corrected logical qubits, far beyond today’s noisy physical devices. The segment visits Microsoft’s Copenhagen quantum lab, where Dr Lauri Sainiemi describes the company’s topological qubit strategy based on Majorana particles, aimed at producing intrinsically stable qubits. By linking holography to quantum hardware, the show highlights a concrete target for qubit counts and showcases one of the field’s most ambitious engineering efforts to achieve it.
