Magnetic engineered quantum systems for sensing and fundamental studies

Many types of quantum systems use mechanical degrees of freedom – and to achieve low decoherence rates researchers have developed a number of ways to levitate quantum systems using either optical forces (optical tweezers), or electro-dynamic forces (ion traps). We have proposed and developed an alternate route using magnetic levitation – which uses no active power and can support macroscopic objects. We discuss some research relating to magnetic trapping and cooling or macroscopic objects, both theory and experiment; how to probe the interaction between gravity and quantum systems; and a novel scheme to achieve a sensing precision which scales better than the quantum Heisenberg limit – a general method useful for extreme metrology.
