[19p-B303-12] Possible improvement of low-dose electron microscopy using flux qubits
Keywords:flux qubit, cryoEM, Heisenberg limit
Electron microscopy, or more broadly charged particle optics, is an area that could benefit from superconducting qubit technologies. Of particular interest is biological cryo-electron microscopy, where the problem of radiation damage necessitates the minimal dose of imaging electrons.
Superconducting qubits are able to generate quantum mechanically superposed electromagnetic potentials around them, generating entanglement with charged particles passing by.
We will describe the scheme to improve low-dose electron microscopy using such an entangling interaction; the amount of expected improvement; and experimental prospects [1-5]. We will also briefly touch upon our experimental effort being undertaken at Akita Prefectural University.
