Laser written circuits for quantum photonics
Open accessAbstract
The femtosecond laser direct‐writing (FLDW) of waveguide circuits in glasses has seen interest from a number of fields over the previous 20 years. It has evolved from a curiosity to a viable platform for the rapid prototyping of small scale circuits. The field of quantum information science has exploited this capability and in the process advanced the fabrication technique. In this review the technological aspects of the laser inscription method relevant to quantum information science will be discussed. A range of demonstrations which have been enabled by laser written circuits will be outlined; these include novel circuits, simulations, photon sources and detection. This places the FLDW technique among the few integrated optical platforms to have produced individually every component required for scalable quantum computation. image

Claims other papers make about this one
Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“For example, let as consider a typical birefringence n s,H -n s,V ≃ 1 × 10 -4 at λ ≃ 815 nm found in femtosecond-laser-written waveguides [42, 43]. The largest photon antibunching (∆ ϕ = π ) is observed for a length mismatch s -T ≃ 4 mm.”
From Equivalence principle and quantum mechanics: quantum simulation with entangled photons (2018) · cites this paper as [42]
Experimental — accuracy not yet measuredThe cited source says what the claim attributes to it.
In the citing paper
“If the waveguide shows a weak birefringence, as it happens for instance in waveguides currently used in integrated quantum photonics circuits [42], the refractive index n s takes slightly different values, n s,H and n s,V , depending on the polarization state (horizontal H or vertical V) of the excitation wave [42,43].”

The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“We experimentally demonstrate our approach by performing tomography of spatially entangled mixed or pure states of two indistinguishable photons, using a specially designed on-chip laser-written waveguide circuit.27”

In the citing paper
“Si-based MZIs with a 65dB on-off ratio has been achieved with near-perfect beamsplitters [41], equivalent to having a Pauli-Z error rate of < 10 -6 [42].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
