Quantum 'miracle material' can store information in a single dimension thanks to newly discovered magnetic switching
- Scientists have discovered a quantum material that can store quantum information using magnetic switching, leading to more viable quantum computing and sensing capabilities.
- Chromium sulfide bromide, likened to filo pastry due to its thin atomic layers, shows promise in information storage through various methods like electric charge, light, magnetism, electrons' spin, and phonons.
- It can store information using excitons, formed when an electron and its hole bind together, leaving behind a hole when a photon moves from its grounded state.
- At lower temperatures, the material's layers are magnetized, whereas it loses magnetization at higher temperatures, allowing excitons to extend over multiple layers.
- In its single-atom-thick form, chromium sulfide bromide confines excitons to a single dimension, potentially allowing for longer storage of quantum information by reducing collisions and decoherence.
- A recent study reported producing excitons in chromium sulfide bromide using infrared light pulses, resulting in different variations of excitons aligned in different directions.
- Magnetic order plays a crucial role in shaping excitons and interactions, potentially revolutionizing future electronics and information technology.
- Researchers aim to explore the conversion of excitons to magnetic excitations in the electronic spin of the material, enabling the conversion of quantum information between subatomic particles.
- The material's ability to switch between magnetized and non-magnetized states may facilitate speedy conversion of photon and spin-based quantum information for future quantum devices.
- Chromium sulfide bromide's properties of storing information through magnetism, along with its abilities in photon information transfer, electron processing, and phonon modulation, hold promise for future quantum devices.
