The New Quantum Era - innovation in quantum computing, science and technologyMechanical Quantum Memories with Mohammad MirhosseiniAssistant Professor Mohammad Mirhosseini (Caltech EE/APh) explains how his group built a mechanical quantum memory that stores microwave-photon quantum states far longer than typical superconducting qubits, and why that matters for hybrid quantum architectures. The discussion covers microwave photons, phonons, optomechanics, coherence versus lifetime (T2 vs. T1), current speed bottlenecks, and implications for quantum transduction and error mechanisms. The discussion centers on a paper from Mirhosseini's paper from December of 2024 titled, “A mechanical quantum memory for microwave photons,” detailing strong coupling between a transmon and a long‑lived nanomechanical oscillator for storage and retrieval of nonclassical states.Gues...

The Quantum Stack WeeklyCaltech's Quantum Memory Leap: Extending Lifetimes, Empowering ApplicationsThis is your The Quantum Stack Weekly podcast.Every week, I’m Leo—the Learning Enhanced Operator, and tonight, I’m bristling with excitement. The quantum world never sleeps, and neither do we. Within just the past 24 hours, Caltech has unleashed a quantum memory advancement that’s causing true ripples across our discipline. Leveraging the atomic ballet of sound waves, their team has expanded quantum memory lifetimes by a factor of thirty—think about it, thirty times the persistence compared to the hottest superconducting qubits we had before.Picture this: in Caltech’s low-temperature lab, researchers like Mohamma...
