- Abstract: The Bell basis, a set of maximally entangled biphoton state, is a critical
prerequisite towards quantum information processing, and many quantum
applications have highlighted the requirement for the manipulation of
high-dimensional Bell basis. While the Bell states can be created by using
ingenious single-photon quantum gates, its implementation complexity in higher
dimensions is significantly increased. Here we present an elaborate approach to
show that the adaptive pump modulation enable the efficient preparation of Bell
basis in arbitrary-dimensional Hilbert space. A complete set of
four-dimensional orbital angular momentum Bell states are experimentally
created, yielding high fidelities for certifying the entanglement
dimensionality. Our strategy can be simply generalized to prepare more complex
forms of quantum states even exploiting other physical degrees of freedom.
Also, it can facilitate the use of high-dimensional entanglement in a variety
of quantum protocols, in particular those requiring quantum dense coding.

The AQuO is then applied in quantum trajectory simulation for quantum subspace stabilization and quantum Zeno dynamics, as well as incoherent manipulation and generalized measurements of the qudit.
