Project description
A big step towards scalable, tuneable quantum systems
Heating of particle trapping mechanisms and decoherence of quantum states are significant challenges in quantum information processing and quantum simulation as they limit the stability and accuracy of quantum systems. Current atom chip designs, which rely on electrical currents to create traps for neutral atoms, generate heat and introduce noise, leading to decoherence and limiting scalability. The ERC-funded ARXIMEDES project plans to develop a novel platform that combines neutral atoms with magnonics – spin waves in magnetic materials – on a compact chip. Researchers will use magnonic fields to trap and control ultracold rubidium atoms, thereby eliminating the need for electrical currents. The team will create a magnonic lattice toolbox to enable precise atom manipulation, with implications for quantum information processing, quantum simulation and quantum sensing.
Objective
ARXIMEDES’ ambition is to establish a novel neutral atom-magnon platform towards on-chip quantum information processing (QIP) and quantum simulation at 300 K. It will explore the braiding of magnonics e.g. spin waves with cold matter: First, by harnessing the spin wave’s tuneable stray field of a standing spin wave pattern to trap ultracold neutral 87Rubidium (Rb) atoms on chip via magnonic lattice potentials. Second, by controlling the atoms & their interactions via magnonics. The absence of electrical current generating the trap will overcome today's challenges of miniaturized atom chips such as heating and decoherence from the trap. Third, the subsequent constitution of a new “magnonic lattice toolbox” which contains all ingredients to individually control and manipulate atoms will pioneer on-chip sensing, QIP and quantum simulation (by exploiting the frequency tunability and phase control of magnonics to move atoms by coupling to spin waves or to tune the lattice for Floquet band engineering). ARXIMEDES’ compact atom-magnon chip will uniquely combine the scalability, tuneability and controllability of magnonics with the advantages of neutral atom qubits (e.g. long coherence times, low error rates). ARXIMEDES will thus establish new avenues for QIP and quantum simulation for many-body physics by studying very short-range atom interaction regimes (via wide lattice spacing tunability for sub-wavelength lattices e.g. to engineer artificial gauge fields). Further, magnon-atom interactions in the linear or nonlinear regimes will be explored for the first time as well as extending state-of-the art magnonics by the new roles of spin wave interference, pulses and propagation in ARXIMEDES. Together with these new insights to fundamental physics, ARXIMEDES unique idea will also propel atom chip quantum sensors beyond state-of-the-art and bring together the cold matter and magnonics communities for new pathways for on chip quantum technologies in the 21st century.
