Embodiments can relate to a flow meter. The flow meter includes a tube having a length L. The flow meter includes a heater wire either wound about the tube or extending through the tube. The flow meter includes an optical fiber extending through the tube. An interrogator is used to interrogate the optical fiber. Electrical power can be supplied to the heater wire. The flow meter is placed in an environment in which fluid (e.g., gas or liquid) is allowed to, caused to, or anticipated to flow over the tube in a direction that is not parallel to the length L of the tube.

A method for authenticating a liquefied gas by exposing a sample of the liquefied gas to a specific excitation wavelength of electromagnetic radiation and detecting a resulting signal with a detector, wherein the specific excitation wavelength is a wavelength at which a marker in an authentic liquefied gas exhibits a distinguishable signal detected by the detector; authenticating said liquefied gas when the resulting signal corresponds to an expected signal provided by the authentic liquefied gas having an authentic marker concentration; and identifying the liquefied gas as suspect or counterfeit when the resulting signal deviates from the expected signal by more than an amount provided by an authentication standard.

The invention relates to a quantum computer, which comprises a sample (21) with paramagnetic centres, preferably in the form of NV centres (22), and a pumping radiation source (1). The pumping radiation source (1) irradiates, by means of an optical system, the paramagnetic centres and/or NV centres (22) with pumping radiation (54) of a pumping radiation wavelength (λ) over a first optical partial path. The optical system detects the fluorescent radiation (33) of the paramagnetic centres (22) and guides the fluorescent radiation (33) to a photodetector (50) and/or a single-photon detector (50) over a second optical partial path. The first optical partial path differs from the second optical partial path at least in some portions. The photodetector (50) and/or the single-photon detector (50) convert the fluorescent signal of the fluorescent radiation (33) of the paramagnetic centres (22) into at least one measurement signal and/or at least one measurement value. The quantum computer uses this at least one measurement signal and/or this at least one measurement value to carry out a quantum operation. The device is characterised in that the quantum computer has an optical spatial filter in the second optical partial path.

A downhole tool is provided that includes radiation shielding using a material that is lighter, stronger, less expensive, and/or more commercially available than tungsten radiation shielding. Such a downhole tool may include an electronic radiation generator that emits photons through a source window located on an outer surface of the downhole tool. A detector may detect at least some of the photons through a detector window. Radiation shielding of the downhole tool may attenuate photons that travel from the electronic radiation generator toward the detector without passing through the detector window. The radiation shielding may include a material that has a density less than 10.5 g/cc and an element of atomic number greater than 40.
