QUANTUM DIAMOND MEMBRANES

Perform experiments on thousands of color centers

Single NV arrays with enhanced optical outcoupling

Make your single NV experiments easy and fast with our NV arrays. These consist of a diamond membrane with arrays of light outcoupling structures mounted on a sapphire frame for easy handling. These structures are shaped to enhance the collection efficiency by more than 10× compared to bulk diamond, significantly increasing the signal-to-noise ratio.

What you can study with QDMs

Quantum emitters and qubits

A scalable, high-brightness platform for solid-state quantum experiments. Large NV arrays with enhanced photon collection enable faster data acquisition, improved signal-to-noise ratio, and highly reproducible results.

  • Study NV, SiV, SnV and other color centers
  • Develop and benchmark pulsed spin-control protocols
  • Run experiments on thousands of emitters
  • Build and test bright single-photon sources
  • Prototype quantum computing and spin-photon interfaces

Accelerate your research with high emitter yield and significantly enhanced brightness.

Nanoscale quantum sensing

Designed for surface-sensitive measurements in chemistry and biology. Deposit your sample directly onto the membrane and probe magnetic signals with nanoscale resolution.

  • Detection of paramagnetic ions and metal complexes
  • Monitoring radical reactions and catalytic processes
  • Nanoscale NMR of molecules at surfaces Abendroth et. al.
  • Imaging spin-labeled biomolecules
  • Sensing magnetic nanoparticles used as biomarkers

Shallow NV centers enable maximum surface sensitivity, making the membrane a powerful platform for studying molecular dynamics, chemical reactions, and biological systems at the nanoscale.

Combine Quantum Diamond Membranes with the Quantum Confocal Microscope (QCFM) to run quantum optics experiments, control single-photon sources, implement qubit protocols, and perform nanoscale surface sensing in chemistry and biology.

Configuration options

Configure the diamond membrane for your experiment

Diamond cut

Choose from ⟨100⟩, ⟨110⟩, or ⟨111⟩ diamond cuts. Select ⟨111⟩ to allow for out-of-plane NV orientation or ⟨110⟩ for in-plane.

Implantation depth

Choose the average NV implantation depth from 5 nm to 50 nm. Deeper NVs have higher coherence while shallower NVs are more sensitive to surface fields and phenomena.

Number of NVs per pillar

Choose between membranes where each pillar hosts on average one or multiple NV centers.

Higher coherence - C12

For measurements that require higher coherences choose the isotopically pure C12 diamonds.

Design

The standard design hosts arrays of pillars arranged on a 1.4x1.4 mm² piece of diamond. Please let us know if you require any alterations to the pillar shape or membrane design.

Special requests

Feel free to ask for any special features such as implantation angle, implantation species, multiple implantations, surface annealing, or higher C13 content.
