What are Paul traps and how are they used in quantum mechanics and quantum application?
Used extensively in quantum mechanics and quantum applications, Paul Traps rely on high-voltage electrical connectivity to confine charged particles.
A Paul trap — named after physicist Wolfgang Paul, Nobel laureate 1989 — is a type of quadrupole ion trap that uses a combination of static and oscillating radiofrequency (RF) electric fields to confine charged particles in three dimensions without physical contact. The alternating quadrupole field, typically operating in the 1–100 MHz range, creates a dynamic pseudo-potential well that prevents ions from escaping along any spatial axis.
How does FEMTOPRINT manufacture Paul traps with through-glass vias (TGVs) for quantum applications?
FEMTOPRINT provides robust trench geometries, through-glass vias (TGVs), masked metallization to enhance dielectric integrity and prevent short circuits.
FEMTOPRINT manufactures Paul trap substrates in fused silica (SiO₂) using femtosecond laser micromachining combined with selective chemical etching. This maskless, direct-write process defines all critical geometries, electrode trenches, via holes, alignment features, in a single monolithic glass piece, eliminating bonding interfaces and the dimensional instability they introduce
What vacuum and quantum state retention performance do FEMTOPRINT Paul traps achieve?
FEMTOPRINT's Paul traps are produced to maintain superior vacuum compatibility, reducing ion loss rates and enhancing long-duration quantum state retention.
FEMTOPRINT's monolithic fabrication approach eliminates all organic materials from the trap structure. There are no epoxies, no solder joints, no polymer insulators, all of which are sources of outgassing and dielectric charging that degrade UHV performance and introduce electric field noise at the ion position.
What are the primary applications of FEMTOPRINT Paul traps and TGVs in quantum technology?
Paul traps produced by FEMTOPRINT serve the most demanding quantum hardware platforms currently in development and production:
Trapped-ion quantum computing
Precision spectroscopy and optical atomic clocks
Quantum sensing and gravimetry
Quantum teleportation and entanglement distribution
