Quantum technology

Neutral atoms and trapped ions

Neutral atoms and trapped ions

Neutral atoms and trapped ions use laser cooling to cool down the atoms or ions, which in turn slows down their motion. Optical tweezers are used to trap neutral atoms while traps such as Penning traps or Paul traps utilize electric fields to create potentials that confine ions. A large number of beam spots can be generated by combining the spatial light phase modulator (LCOS-SLM) with an appropriate phase pattern and optical system. Trapping neutral atoms at those spot positions allows neutral atoms to be arranged in any array configuration. Neutral atoms and trapped ions can be configured in a "superposition state," which means that their state is encoded using both the “0” state and “1” state also known as a qubit. Trapped ions’ and neutral atoms’ positions are monitored using a high-sensitivity camera. Observing the fluorescence, or lack thereof, for trapped ions and neutral atoms indicates the state of the qubit. Photon counting detectors such as PMTs are typically used for reading out the qubit state of trapped ions while EM-CCD cameras are used for reading out the qubit state of neutral atoms. Quantum mechanical behavior can be manipulated to realize applications such as quantum computing and quantum simulations.

ORCA-Quest camera

The world's first camera to incorporate the qCMOS image sensor and to be able to resolve the number of photoelectrons using a newly developed dedicated technology.

ORCA-Fusion BT digital CMOS camera

The ORCA-Fusion BT digital CMOS camera enables quantitative detection of weak fluorescent light from trapped ions and neutral atoms. The camera’s low noise floor, high QE, and zero excess noise factor due to gain make it an attractive option for neutral atom qubit readout as well as monitoring trapped ions.

LCOS-SLM (optical phase modulator) X15213 series

The LCOS-SLM is a reflective spatial light modulator that freely controls the phase of light with a liquid crystal. Controlling the phase (wavefront) with LCOS-SLM enables researchers to generate a highly efficient optical microtrap array.

Photon counting head H10682 series

The photon counting head H10682 series is a module that enables photon counting measurement of ion fluorescence with high sensitivity and low noise.

64ch multianode PMT assembly H12428 series

The 64-channel multianode PMT assembly H12428 series is an assembly that can detect fluorescence of multiple ions in a 64-channel matrix.

32-channel linear array multianode PMT module H11460 series

The 32-channel linear array multianode PMT module H11460 series is a low crosstalk module that can detect fluorescence of multiple ions with a 32-channel linear array. (The photon counting module H12211 is also available.)

Hybrid photodetectors (HPDs)

The HPD is a photodetector that can detect fluorescence with high sensitivity, fast response, and low jitter. HPDs maximize quantum efficiency and have lower excess noise than PMTs, resulting in better signal-to-noise ratio than PMTs.
