    摘要： A method and system for driving a set of qubits (Q1,Q2). A first qubit (Q1) is provided with a first driving frequency (F1) and a second qubit (Q2) is provided with a second driving frequency (F2). Each qubit (Q1,Q2) is provided with a separate microwave gate (G1,G2) configured to apply a respective microwave signal (W1, W2). A first electrical signal (E1) comprising the first driving frequency (F1) is applied to the first microwave gate (G1) for driving the first qubit (Q1). Simultaneously a second electrical signal (E2) is applied to the second microwave gate (G2) comprising the first driving frequency (F1) shifted in phase with respect to the first electrical signal (E1) for generating the second microwave signal (W2) with the first driving frequency (F1) arriving at the second qubit (Q2) in counterphase to first microwave signal (W1). This may at least partially compensate crosstalk.

    摘要： A system for managing a data stream between first and second networks is described in which a node entity transmits a data stream addressed to a destination device in the second network and a gateway entity receives the data stream from the first network. The gateway entity identifies at least one characteristic of the destination device and transmits it to the node entity in the first network in such a way that the characteristic is relatable to the data stream. The node entity receives the characteristic of the destination device from the gateway entity and relates it to the data stream and performs Quality of Service management on the data stream based on the at least one characteristic. A gateway device and a method of managing a data stream are also described. The system, gateway, node and method extend the application of QoS performance and management.

    摘要： A method and device (10) for making a calibrated measurement of light from an object (E). In a first measurement window (W1), object light (L E ) is received from the object (E) onto a beam splitter (11) which splits the light into a signal path (Ps) and a reference path (Pr). A first signal (S1=T.L E .Hs) is measured by a signal detection element (15s) in the signal path (Ps). A second signal (S2=R-L E -Hr) is measured by a reference detection element (15r) in the reference path (Pr). In a second measurement window (W2), calibration light (L C ) is received onto the beam splitter (11). A third signal (S3=R·L C ·Hs) is measured by the signal detection element (15s) in the signal path (Ps). A fourth signal (S4=T·L C ·Hr) is measured by the reference detection element (15r) in the reference path (Pr). A measurement value of the object light (L E ) is determined based on the measured signals (S1,S2,S3,S4).
