The blue dipole guide and red lattice continue to provide a background radial trap. The RSBC laser is blue-detuned 50 GHz from the \(\leftF=1\right\rangle \leftrightarrow \left{F}^{{\prime} }=2\right\rangle \) transition so that atoms are trapped at the nodes of the triangular lattice, suppressing scattering off the cooling beams. 19.

A bias magnetic field of 0.11 G along \(\hat{Z}\) is applied to match the first-order Zeeman splitting to the trap frequency ω tri .5% to $171 in the same period, suggesting that many traders have been securing their profits. The polarizations of the three beams are twisted 10° from the vertical to create the Raman coupling for driving the vibrational mode transition \(\leftF=1,{m}_{F},{n}_{{\rm{tri}}}\right\rangle \to \leftF=1,{m}_{F}-1,{n}_{{\rm{tri}}}-1\right\rangle \) that reduces the vibrational quantum number n in the local traps.

After three cooling cycles, we slowly turn off the remaining red lattice and the RSBC lattice over 3 ms so that the atoms start to free fall.

But, given the existing profit-taking sentiment, the level may not hold for long, which could result in an extended decline toward the $137-$150 support range. State transfer with a microwave pulse may be used for future improvement to reduce heating associated with optical pumping.

Atomic and cavity probe lasers To stabilize the frequencies of the Raman lasers and the atomic probe relative to the cavity, we frequency lock a separate cavity probe laser to the cavity and then perform offset frequency phase locks to this laser.382 and 0. The cavity probe is locked to a cavity TEM 00 mode approximately 160 GHz to the blue of the atomic transition frequency ω a such that this mode is essentially unperturbed by the presence of atoms. The locking of the cavity probe to the cavity is done by a Pound–Drever–Hall lock at very low phase modulation index for a single sideband to carrier power ratio of 10 −4 .

Therefore, a break below $185 could have QNT bears eye $137, a 25% drop, as the ultimate downside target by the end of the month. Rather than locking to the carrier, we lock to the weak sideband.

This enables us to reduce the amount of power entering the cavity to only 400 pW (half from the sideband and half non-resonantly from the carrier) while still operating above the technical noise floor of the photodiode.

To allow phase locking of other lasers to the cavity probe with relative beat notes of less than 2 GHz, some of the laser light is passed through a fibre EOM driven strongly at 13. Meanwhile, addresses holding between 1,000 QNT and 10,000 QNT tokens also fell, suggesting that the plunge in the 100-1,000 QNT cohort was due to token distribution, not accumulation.6 GHz to generate very high order sidebands.

The offset phase-lock frequency is adjusted to maintain the atomic probe laser approximately δ /2π + 80 MHz blue of ω a . We derive three important tones from this laser: a homodyne reference beam, a path length stabilization beam used for removing path length noise and drift, and the actual atomic probe tone used for OAT and QND measurements..

The path length stabilization beam is passed through an EOM that is modulated at 80 MHz to create a weak sideband that will serve as the atomic probe tone. The combined path length stabilization and atomic probe tones are reflected from the cavity and detected on a single homodyne detector. The homodyne reference beam is shifted by an 80 MHz AOM to have the same frequency as the atomic probe tone.

The quadrature of the atomic probe tone that we detect in the homodyne is actively stabilized by adjusting the phase of the homodyne reference tone. This is achieved by detecting the phase of the path length stabilization tone appearing in the homodyne detector at 80 MHz and then holding this phase constant by feedback on the frequency of the 80 MHz AOM used to shift the homodyne reference beam.

The laser could be actively locked to the dressed resonance as in ref. 5 or the linear part of the dispersive could be used to estimate small frequency shifts, but for this work we sweep the atomic probe laser, and all derived beams, so that the atomic probe tone sweeps through cavity resonance at 1.

Including this loss of efficiency, the net effective quantum efficiency is approximately 10%. When using the atomic probe to drive OAT, it is ideal to operate with the driving laser detuned from cavity resonance by δ = κ /2 to suppress free-space scattering.

However, we work at larger detunings for two reasons. First, an increased detuning reduces deleterious QND interactions (or, equivalently, photon shot noise from the applied drive tone) that were neglected in our description of the emergence of the unitary dynamics .
