quantum layer
This layer contains the NV centers that host the quantum behavior, enabling the system to harness quantum effects.
intrinsic layer
NV centers must be well separated from sources of quantum noise elsewhere in the diamond because nearby doped layers, such as phosphorus-rich regions with free electrons, can cause decoherence.
N-/p-type layer
Doped diamond layer that enables electrical control of charge and fields, which is essential for stabilizing NV centers and operating diamond quantum devices. This allows photo-electric readout and ensures long coherence times.
diamond chip base layer
The diamond chip base layer, sourced externally, must meet strict material specifications to enable quantum applications.
