Abstract
Aspects of the present disclosure describe an atomic oven including a cathode, an anode that comprises a source material, and a power supply that provides a voltage between the cathode and the anode, wherein applying the voltage causes multiple electrons from the cathode to ablate the source material from the anode or locally heat the anode to cause source material to evaporate from the anode and, in both case, to produce a stream of ablated or evaporated particles that passes through an opening in the cathode.
Claims20
An atomic oven, comprising:
- a cathode;
- an anode that comprises a source material;
- and
- a power supply that provides a voltage between the cathode and the anode, wherein an application of the voltage causes a plurality of electrons from the cathode to ablate or evaporate the source material from the anode to produce a stream of ablated or evaporated particles having at least one of neutral particles or charged particles, the stream passing through an opening formed by the cathode.
A quantum information processing (QIP) system for controlling quantum states of ions in an ion chain to perform a quantum operation, comprising:
- a trap configured to trap the ions to implement the ion chain;
- and
- an atomic oven that provides a stream of ablated or evaporated particles having the ions for trapping by the trap, comprising:
- a cathode;
- an anode that comprises a source material;
- and
- a power supply that provides a voltage between the cathode and the anode, wherein an application of the voltage causes a plurality of electrons from the cathode to ablate or evaporate the source material from the anode to produce a stream of ablated or evaporated particles having at least one of neutral particles or charged particles, the stream passing through an opening formed by the cathode.
A method, comprising:
- applying a voltage between a cathode and an anode;
- ablating or evaporating the anode to sputter materials off of the anode;
- and
- providing a plasma stream produced through an opening of the cathode, wherein the plasma stream includes a portion of the materials sputtered off or evaporated off of the anode.
