The invention relates to a device for sorting articles (16) providing at least one path (12, 14) along which the articles can be moved, said path comprising a first sliding surface (24) having a front end (30) and a second sliding surface (26) positioned downstream of the first sliding surface and having a rear end (34).According to the invention, said first and second sliding surfaces (24, 26) have predetermined widths and a plane (32) tangent to the second sliding surface at the rear end thereof includes an angle of less than 180° with a plane (36) tangent to the first sliding surface at the front end thereof, a stop (38) being positioned at a predetermined distance from said front end of said first sliding surface.

A method for quantum error detection and/or correction according to a quantum error correction code that comprises at least one stabilizer operator acting on at least two data qubits (11), the method comprising: providing a quantum hardware (100, 100', 1000, 1000a, b, c, d, e) which comprises the at least two data qubits (11), a syndrome qubit (12a, b) and a multiqubit coupler (1) for the qubits (11, 12a, b); operating the qubits (11, 12a, b) and the multiqubit coupler (1) according to a syndrome measurement circuit associated with the at least one stabilizer operator to thereby retrieve an error syndrome of a quantum state of the data qubits (11) associated with the at least one stabilizer operator.

There is provided a tape repair jig for a slide fastener. The slide fastener includes: a pair of element rows; a pair of tapes configured to be in a good state and a defective state; and a slider. In the good state, side edge portions of the pair of tapes that face each other become a pair of raised portions, and a groove portion is formed between the pair of raised portions. In the defective state, the side edge portions of the pair of tapes that face each other overlap with each other vertically. The tape repair jig includes an attachment portion, a gripping portion, and a protruding portion configured to repair the defective state to the good state. The protruding portion is insertable into the groove portion.

The present invention is related to a computer-implemented method and a system for estimating a ground state property of a quantum system, to a computer program product and a data carrier.

The present invention is related to a method for mitigating errors caused by noise in a target quantum circuit executed by a quantum processor, to a computer program product and a computing system for carrying out the method and to a data carrier having stored thereon the computer program.

A hydrogen aircraft utilizes hydrogen as fuel for a power unit. The hydrogen aircraft includes target piping and a cooling device. The target piping is piping for transportation of liquid hydrogen, and has a stagnation period during which liquid hydrogen does not substantially flow while the hydrogen aircraft is in operation. The cooling device cools the target piping.

A device (100) for calibrating an X-ray system (200) with an X-ray source (210) and an X-ray detector (220), the calibration device (100) comprising a set of at least two X-ray absorptive elements (1, 2), each element (1, 2) extending in a longitudinal (LO) and in a lateral (LA) direction, is according to the invention characterized in that the device (100) is configured to enable adjustment of the position of each element (1, 2) along a closed curve (C₁, C₂) in a plane that extends transverse to the lateral direction (LA) and in parallel to the longitudinal direction (LO) so that elements (1, 2) in each of a first and a second subset (10, 20) of the set of elements (1, 2) are positioned with their longitudinal directions (LO) aligned in an alignment direction transverse to the curve (C₁, C₂), and wherein a first total length in the longitudinal direction (LO) of the elements (1, 2) of the first subset (10) is different from a second total length in the longitudinal direction (LO) of the elements (1, 2) of the second subset (20).
