“…10 We envisage that a similar phenomenon is occurring in our system, as evidenced by the resonance at specific conditions and is indicative of wave-like behaviour. 43 Thus, we suggest that the electron transfer is a QBET, and this is the first example of an electrically stimulated QBET in biology to date and consequently facilitating electrical-molecular communication.…”

Quantum biological electron tunnelling (QBET) underpins cellular behaviour. Control of electrical-molecular communication could revolutionise the development of disruptive technologies for understanding and modulating molecular signalling. Current communication technology is not appropriate for interfacing with cells at a spatial/temporal level equivalent to the native biological signalling. We merge bipolar nano-electrochemical tools with cancer cells. Gold-bipolar nanoelectrodes functionalised with electron acceptor-donor-species, were developed as electric field bio-actuators we term bio-nanoantennae. Remote electrical input regulated electron transport between the acceptor-donor species at the bio-nanoantennae in a selective manner. The wireless modulation of electron transport results in QBET triggering apoptosis in patient-derived cancer cells representing electrical-molecular communication. Transcriptomics data highlight the electric field targets the cancer cells in a unique manner. The stated insight and invention open a plethora of applications in healthcare. This may lead to new quantum-based medical diagnostics and treatments, as well as understanding of the biological physics.

“…Moreover, the emitted light from the molecular excitonic mode can also be squeezed, along with the plasmon mode. Our results are of immediate relevance to STM single molecular junctions aiming to detect and control plasmon-enhanced light–matter interactions − and take an important step toward the realization of quantum information processing using single molecules.…”

Plasmon Squeezing in Single-Molecule Junctions

Scanning tunneling microscope (STM)-induced luminescence provides an ideal platform for electrical generation and the atomic-scale manipulation of nonclassical states of light. However, despite its extreme importance in quantum technologies, squeezed light emission with reduced quantum fluctuations has hitherto not been demonstrated in such a platform. Here, we theoretically predict that the emitted light from the plasmon mode can be squeezed in an STM single molecular junction subject to an external laser drive. Going beyond the traditional paradigm that generates squeezing with the quadratic interaction of photons, our prediction explores the molecular coherence involved in an anharmonic energy spectrum of a coupled plasmon−molecule−exciton system. Furthermore, we show that, by selectively exciting the energy ladder, the squeezed plasmon can show either sub-or super-Poissonian statistical properties. We also demonstrate that, following the same principle, the molecular excitonic mode can be squeezed simultaneously.

“…Such independent dimers have proven to be highly emissive. [43][44][45][46][47][48] Furthermore, each dimer was surrounded by four alkyl carbazoles. The four carbazole planes were distributed on both sides of the dimer and perpendicular to the dimer plane under the driving force of multiple C-HÁ Á Áp interactions and hydrogen bonding with distances of 2.7-3.0 Å (Fig.…”
