Abstract: LED lamps and/or LED lighting devices including LED lamps are provided. An LED lamp includes two or more sets of LED packages. Each set of LED packages comprises at least one respective LED package. The two or more sets of LED packages comprising a first set of LED packages and a second set of LED packages. The LED lamp further includes a first optical element configured to control light dispersion of light emitted by the first set of LED packages; and at least one additional optical element configured to control light dispersion of light emitted by the second set of LED packages.

Abstract: Systems and methods are provided for flux control of a qubit. A quantum system includes a microwave transmitter configured to provide a continuous microwave tone, and a qubit configured such that a portion of an energy spectrum of the qubit is responsive to an applied flux. The qubit also has an inductive element responsive to the continuous microwave tone to produce a Rabi oscillation within the qubit. A flux source is configured to apply a flux to the qubit.

Abstract: Security unit, particularly for storing payments in a retail outlet, comprising a secure, lockable housing with an inlet, a gas feed mechanism for conveying items introduced into the housing, and a removable package for receiving and storing payments. Before the package can be removed, the package is sealed in a tamper evident manner. The package is preferably a plastics container having a neck portion extending from its inlet, and gas outlets remote from the inlet through which gas introduced into the inlet is vented. The feed mechanism preferably comprises a channel through which payments are conveyed and gas inlets provided on opposed sides of the channel, inclined at an angle to that in which the items are conveyed. Gas is jetted through the channels to produce a gas flow which entrains an item to convey this through the channel.
