An anonymous reader quotes a report from Ars Technica: There's a general consensus that we won't be able to consistently perform sophisticated quantum calculations without the development of error-corrected quantum computing, which is unlikely to arrive until the end of the decade. It's still an open question, however, whether we could perform limited but useful calculations at an earlier point. IBM is one of the companies that's betting the answer is yes, and on Wednesday, it announced a series of developments aimed at making that possible. On their own, none of the changes being announced are revolutionary. But collectively, changes across the hardware and software stacks have produced much more efficient and less error-prone operations. The net result is a system that supports the most complicated calculations yet on IBM's hardware, leaving the company optimistic that its users will find some calculations where quantum hardware provides an advantage. [...] Wednesday's announcement was based on the introduction of the second version of its Heron processor, which has 133 qubits. That's still beyond the capability of simulations on classical computers, should it be able to operate with sufficiently low errors. IBM VP Jay Gambetta told Ars that Revision 2 of Heron focused on getting rid of what are called TLS (two-level system) errors. "If you see this sort of defect, which can be a dipole or just some electronic structure that is caught on the surface, that is what we believe is limiting the coherence of our devices," Gambetta said. This happens because the defects can resonate at a frequency that interacts with a nearby qubit, causing the qubit to drop out of the quantum state needed to participate in calculations (called a loss of coherence). By making small adjustments to the frequency that the qubits are operating at, it's possible to avoid these problems. This can be done when the Heron chip is being calibrated before it's opened for general use. Separately, the company has done a rewrite of the software that controls the system during operations. "After learning from the community, seeing how to run larger circuits, [we were able to] almost better define what it should be and rewrite the whole stack towards that," Gambetta said. The result is a dramatic speed-up. "Something that took 122 hours now is down to a couple of hours," he told Ars. Since people are paying for time on this hardware, that's good for customers now. However, it could also pay off in the longer run, as some errors can occur randomly, so less time spent on a calculation can mean fewer errors. Despite all those improvements, errors are still likely during any significant calculations. While it continues to work toward developing error-corrected qubits, IBM is focusing on what it calls error mitigation, which it first detailed last year. [...] The problem here is that using the function is computationally difficult, and the difficulty increases with the qubit count. So, while it's still easier to do error mitigation calculations than simulate the quantum computer's behavior on the same hardware, there's still the risk of it becoming computationally intractable. But IBM has also taken the time to optimize that, too. "They've got algorithmic improvements, and the method that uses tensor methods [now] uses the GPU," Gambetta told Ars. "So I think it's a combination of both."

Russia's gold reserves reached a new record in August as they amounted to $188.8 billion. Their share in international assets exceeded 30 percent for the first time in almost 25 years, the Central Bank of Russia said. As of September 1, 2024, Russia's international reserves grew to $613.7 billion, up from $602.05 billion as of August 1. In August, Russia increased its gold investments by 5.1 percent, bringing them to a record $188.8 billion. The previous record was set a month earlier at $179.5 billion.

Earth requires fuel to drive plate tectonics, volcanoes and its magnetic field. Like a hybrid car, Earth taps two sources of energy to run its engine: primordial energy from assembling the planet and nuclear energy from the heat produced during natural radioactive decay. Scientists have developed numerous models to predict how much fuel remains inside Earth to drive its engines -- and estimates vary widely -- but the true amount remains unknown.

Responding to your feedback, we are now proud to present new separate parameters for noise, reverb, and breath reduction to give you more flexible control for your individual, best output results.
Find all the new parameters below and listen to the Audio Examples to get a closer impression of the upgrade.

What's the update about?

Before

Previously, you could only set the Denoising Method and one reduction amount, that was used for all elements.
Depending on the selected method, you were already able to decide whether music, static, or changing noises should be removed, but there was no setting to keep the typewriter sound effects while removing the reverb, for example.

Now

With our latest upgrade, you can now set the reduction amounts separately for noise, reverb, and breathing sounds.
For example, you could completely remove the background noise while reducing the reverb just a little to enhance speech intelligibility but keep the atmosphere. Like we did in Audio Example 1.
Many of you have also asked about the possibility of slightly reducing breath sounds rather than eliminating them completely. In Audio Example 2 we demonstrate how you can prevent your audio from sounding strange and unnatural by reducing instead of eliminating all breathing sounds.

To all of you who are happy with the results and don't want anything to change, relax:
If you don't change the default settings, the noise reduction algorithms work exactly the same as before.

Note: As the 'Static Denoiser' removes only stationary noise, there are no 'Remove Reverb' and 'Remove Breathings' parameters available for this denoising method.

New Parameters

Screenshot of the new Noise Reduction Parameters in the production form.

In order to use the new noise reduction features, you may separately set the following parameters:

• Denoising Method: (unchanged) Select what kind of noise you want to remove.
  [Dynamic Denoiser (default), Speech Isolation, Static Denoiser]
  Note that the parameters 'Remove Reverb' and 'Remove Breathings' are NOT available for Static Denoiser!
• Remove Noise: Select the amount of noise you want to remove.
  [100 dB (default), Disable Denoise, 3 dB, 6 dB, ..., 100 dB (full)]
• Remove Reverb: Select the amount of reverb you want to remove.
  [100 dB (default), Disable Deverb, 3 dB, 6 dB, ..., 100 dB (full)]
• Remove Breathings: Select the amount of breathings you want to remove.
  [Off (default), 3 dB, 6 dB, ..., 100 dB (full)]

Feel free to experiment with all the options to find your preferred parameter settings! Editing and reprocessing existing productions does not cost any additional credits as long as you don't change the input file.

Listen to the results:

1. Reverb reduction with full noise elimination

For the first audio example by conduitministries.com we set the 'Remove Noise' amount to 100 dB (full) and varied the 'Remove Reverb' amount starting from 0 dB (Off) to 12 dB (medium) and to 100 dB (full). Listen to how first the noise is gone and then step by step the reverb is lower:

2. Breathing sound reduction

In the breathing reduction audio example by LibriVox.org we used the 'Remove Breathing' amounts increasing from the original audio with 0 dB (Off) to 12 dB (medium) and to 100 dB (full) reduction.
In the result files you can hear, that the 100 dB (full) elimination leads to weird, unnatural-sounding pauses, that can be prevented by just reducing the breathing sounds:

Theodore J. Flicker's 1967 James Coburn satire The President's Analyst is one of my very favorite spy movies. (It's also Coburn's best spy movie... Sorry, Derek Flint.) When describing it to people, I always say that the comedy holds up surprisingly well today... sadly. America is still facing many of the same social  issues Flicker sent up over fifty years ago (from institutional racism to monolithic Big Tech), and it's easy to imagine a remake. Now, Paramount is imagining one... with The Daily Show host Trevor Noah on board to produce and potentially star. According to The Hollywood Reporter, former Obama White House staffer Pat Cunnane will write the script. The premise, about a psychotherapist burdened with all of the President's top secret stresses, will obviously be familiar ground for him! According to his publisher, Cunnane served as "President Barack Obama’s senior writer and deputy director of messaging at the White House, where he worked for six years in many roles."
