Abstract
Aspects of the present disclosure may include a method and/or a system for applying, to one or more ions in an ion chain, a first light beam having a first polarization and a second light beam having a second polarization to transfer the one or more ions from a first state of a first manifold to a second state of the first manifold, applying, to the one or more ions, the first light beam and the second light beam to transfer the one or more ions from the second state back to the first state, and applying, to the one or more ions, a third light beam to transition the one or more ions from the first state to a third state in a second manifold.
Claims21
A method of Raman addressing in a quantum information processing (QIP) system, comprising:
- applying, to one or more ions in an ion chain, a first light beam having a first polarization and a second light beam having a second polarization to transfer the one or more ions from a first state of a first manifold to a second state of the first manifold, wherein the one or more ions in the first state includes a first angular momentum different than a second angular momentum in the second state;
- applying, to the one or more ions, the first light beam and the second light beam to transfer the one or more ions from the second state back to the first state;
- and
- applying, to the one or more ions, a third light beam to transition the one or more ions from the first state to a third state in a second manifold.
A non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors of a quantum information processing (QIP) system, cause the one or more processors to:
- control a first light source to apply, to one or more ions in an ion chain, a first light beam having a first polarization and a second light beam having a second polarization to transfer the one or more ions from a first state of a first manifold to a second state of the first manifold, wherein the one or more ions in the first state includes a first angular momentum different than a second angular momentum in the second state;
- control the first light source to apply, to the one or more ions, the first light beam and the second light beam to transfer the one or more ions from the second state back to the first state;
- and
- control a second light source to apply, to the one or more ions, a third light beam to transition the one or more ions from the first state to a third state in a second manifold.
A quantum information processing (QIP) system, comprising:
- a first light source configured to:
- apply, to one or more ions in an ion chain, a first light beam having a first polarization and a second light beam having a second polarization to transfer the one or more ions from a first state of a first manifold to a second state of the first manifold, wherein the one or more ions in the first state includes a first angular momentum different than a second angular momentum in the second state;
- and
- apply, to the one or more ions, the first light beam and the second light beam to transfer the one or more ions from the second state back to the first state;
- and
- a second light source configured to:
- apply, to the one or more ions, a third light beam to transition the one or more ions from the first state to a third state in a second manifold.
