Testing Bell’s inequality with ballistic electrons in semiconductors

Abstract

We propose an experiment to test Bell's inequality violation in condensed-matter physics. We show how to generate, manipulate, and detect entangled states using ballistic electrons in Coulomb-coupled semiconductor quantum wires. Due to its simplicity (only five gates are required to prepare entangled states and to test Bell's inequality), the proposed semiconductor-based scheme can be implemented with currently available technology. Moreover, its basic ingredients may play a role towards large-scale quantum-information processing in solid-state devices.

FINDING: New rules for Bell inequalities unify quantum entanglement tests, with a proposed condensed-matter experiment using ballistic electrons in semiconductor quantum wires. | MATH: CHSH inequality form: \( S = E(a,b) + E(a,b') + E(a',b) - E(a',b') \leq 2 \) (classical bound); quantum violation up to \( 2\sqrt{2} \approx 2.828 \); proposed system uses five gates to generate entangled states via Coulomb coupling in quantum wires. | CONNECTION: The ratio \( 2.828 / 2 = 1.414 \) (√2) appears, linking to the diagonal of a unit square — a fundamental geometric symmetry. No direct evidence of 0.382, 0.618, 0.786, 1.618, 2.618, base-60, or crystallographic symmetries in these findings. | DEPTH: 6 — advances understanding of entanglement in condensed-matter systems, but no new fundamental constants or geometric harmonies beyond √2.

Verifying Atom Entanglement Schemes by Testing Bell's Inequality

Dimitris G. Angelakis, Almut Beige, P. L. Knight +2 more

Recent experiments to test Bell's inequality using entangled photons and ions aimed at tests of basic quantum mechanical principles. Interesting results have been obtained and many loopholes could be closed. In this paper we want to point out that tests of Bell's inequality also play an important role in verifying atom entanglement schemes. We describe as an example a scheme to prepare arbitrary entangled states of N two-level atoms using a leaky optical cavity and a scheme to entangle atoms inside a photonic crystal. During the state preparation no photons are emitted and observing a violation of Bell's inequality is the only way to test whether a scheme works with a high precision or not.

Quantum information processing and entanglement in solid state devices

Shiro Kawabata

Control over electron-spin states, such as coherent manipulation, filtering and measurement promises access to new technologies in conventional as well as in quantum computation and quantum communication. In this paper, we review recent theoretical proposal of using electron spins in quantum confined structures as qubits. We also present a theoretical proposal for testing Bell’s inequality in nano-electronics devices. We show that the entanglement of two electron spins can be detected in the spin filter effect in the nanostructure semiconductor/ferromagnetic semiconductor/semiconductor junction. In particular, we show how to test Bell’s inequality via the measurement of the current-current correlation function in this setup.
